關於藉由具有突起部之溫熱器具將人體等生物體之表層局部更充分地溫熱，存在需求。然而，就專利文獻1之溫熱器具而言，於實現此種要求之方面仍有改善之餘地。 本發明係關於一種可將人體等生物體之表層局部充分地溫熱之構造之溫熱器具。 以下，使用圖式對本發明之較佳之實施形態進行說明。再者，於所有圖式中，對同樣之構成要素附上相同之符號，適當省略重複之說明。 [第1實施形態] 如圖1至圖4中之任一者所示，本實施形態之溫熱器具100具備：片材10，其具有向一面10a側凸狀彎曲且另一面10b側成為空腔13之突起部12；及發熱材30，其被填充於突起部12之空腔13。 藉由以突起部12被壓接於皮膚之狀態將溫熱器具100貼合於人體等生物體，可一面利用突起部12按壓生物體之皮膚，一面將生物體之皮膚中與突起部12對應之部位局部充分地溫熱。 即，可將人體等生物體之表層局部充分地溫熱。 藉此，例如，藉由對皮膚之下層之筋膜為止賦予利用突起部12之按壓及利用發熱材30之溫熱之刺激，可如針灸般，藉由按壓及溫熱而對經絡或經穴進行刺激。再者，溫熱器具100於使用前之狀態下，被密閉收容於未圖示之包裝材料內。當將包裝材料開封，並自包裝材料取出溫熱器具100時，外部大氣中所包含之氧被供給至發熱材30，藉此，該發熱材30會發熱。 片材10具備平坦之片狀之基部11及複數個突起部12，該等複數個突起部12係以基部11為基準向片材10之一面10a側凸狀彎曲。 溫熱器具100具備本體部50，該本體部50被貼於生物體之皮膚中欲賦予溫熱之部位。 本體部50例如具備以下構件而構成，即：片材10；發熱材30(圖3)，其被填充於片材10之突起部12之空腔13內；第2片材20(圖3)，其相對於片材10積層於另一面10b側；及吸水片材40(圖3)，其積層於第2片材20與基部11之間。再者，根據發熱材30之組成等，溫熱器具100亦可不具備吸水片材40。 於以下之說明中，存在如下情況，即：對於本體部50，將突起部12之突出方向(圖3中之下方)稱為前表面側，且將與突起部12之突出方向相反之方向(圖3中之上方)稱為後表面側。 本體部50之平面形狀並無特別限定，例如，如圖2所示，可設為4個角部分別被製成倒角形狀之矩形(例如正方形)。但，本體部50之平面形狀亦可為除矩形以外之多邊形、圓形及橢圓形等其他形狀。 片材10構成本體部50之前表面側之外表面。例如，於片材10(尤其是突起部12)與生物體之皮膚直接接觸之狀態下使用溫熱器具100。 於本實施形態之情形時，片材10包含1層不織布片材15(圖4)。 又，第2片材20構成本體部50之後表面側之外表面。 片材10與第2片材20例如形成為相互相同之平面形狀，並且呈相互之外形線一致之狀態重疊，且相互之周緣部彼此接合。 藉此，於片材10之基部11與第2片材20之間保持吸水片材40。 又，於片材10之突起部12之內周面與吸水片材40之間保持發熱材30。 發熱材30例如包含可氧化性金屬、保濕劑及水而構成。藉由對發熱材30中之可氧化性金屬供給氧，發熱材30發熱。 又，發熱材30亦可為含有鐵及碳成分者。 此處所言之鐵既可為上述可氧化性金屬之至少一部分，亦可與上述可氧化性金屬不同。此處所言之鐵為可氧化性鐵。 又，此處所言之碳成分亦可為上述保濕劑之至少一部分，發熱材30亦可於上述保濕劑之外另行包含碳成分。 於本體部50中，亦可為除於與片材10之突起部12對應之部位填充有發熱材30以外，於與基部11對應之部位亦在片材10與第2片材20之間填充有發熱材30。但，於此情形時，亦較佳為與片材10之突起部12對應之部位之發熱材30之厚度大於與基部11對應之部位之發熱材30之厚度。 更佳為，於與片材10之突起部12對應之部位局部地填充有發熱材30，於與基部11對應之部位之至少一部分不存在發熱材30。 於本實施形態之情形時，於片材10中在與突起部12對應之部位填充有發熱材30，與此相對，於與基部11對應之部位實質上不存在發熱材30。 發熱材30較佳為於空腔13內至少填充於與突起部12之前端部對應之部位。藉此，可藉由突起部12之前端部將生物體之皮膚溫熱。 例如，較佳為於空腔13之高度方向上，於自圖4中之下端側起50%以上之區域(與圖4中高度尺寸H2所示之範圍之下半部分對應之區域)填充有發熱材30。 更詳細而言，於本實施形態之情形時，發熱材30例如被填充於空腔13之高度方向上之70%以上之區域。即，如圖4所示，相對於空腔13之高度尺寸H2，於空腔13內填充有發熱材30之區域之高度尺寸成為0.7H2以上。 藉此，可將突起部12更充分地進行加熱，且可藉由突起部12將生物體之皮膚充分地溫熱。 發熱材30進而較佳為例如被填充於空腔13之高度方向上之90%以上之區域。即，於空腔13內填充有發熱材30之區域之高度尺寸進而較佳為成為0.9H2以上。 如此，空腔13之高度方向上之發熱材30之填充率較佳為70%以上，進而較佳為90%以上。 於本實施形態之情形時，例如，片材10之基部11之後表面(圖4中之上表面)與發熱材30之後表面(圖4中之上表面)相互成為同一平面。 此處，對空腔13之高度方向上之發熱材30之填充率的測定方法進行說明。 作為測定器，使用可測定高低差之雷射顯微鏡或雷射位移計。作為雷射位移計，可使用一維之光點型、二維雷射位移計及三維雷射位移計等。根據突起部12之形狀及高度尺寸，基於所要求之測定距離及雷射光之光點距離而選擇適當之雷射位移計。例如，可使用KEYENCE公司製造之感測器頭；IL-300(測定距離160 mm~450 mm，光點直徑f500 μm)。 為了進行測定，以不使發熱材30發熱之方式，於氮氣氛圍中，自溫熱器具100取出本體部50，且自片材10去除第2片材20及吸水片材40，使空腔13內之發熱材30之突起部12之基端側之面(圖4中之發熱材30之上表面)露出。 利用測定器之測定係以對片材10垂直地照射雷射光之方式進行。於該測定中，對發熱材30之突起部12之基端側之面(圖4中之發熱材30之上表面)與片材10之另一面10b之高低差進行測定。此時，以雷射光通過發熱材30之突起部12之基端側之面的中心之方式，使雷射光於該面之直徑方向(亦與突起部12之直徑方向一致)上進行掃描，而求出高低差之最大值。此時，掃描距離係設定為較突起部12之直徑長之距離。 發熱材30之高度尺寸係設為藉由自圖4所示之高度尺寸H2減去藉由測定而求出之高低差之最大值所得之值。 此處，於突起部12之內周面之形狀與突起部12之外周面之形狀(空腔13之外周面之形狀)實質上相等之情形時，作為高度尺寸H2，為方便起見，可使用圖4所示之高度尺寸H1。 即，發熱材30之高度尺寸係設為藉由自高度尺寸H1減去藉由測定而求出之高低差之最大值所得之值。 因此，以如下方式測定高度尺寸H1。即，將片材10之正背以與上述高低差之測定時反轉之方式配置，以通過突起部12之頂點之方式求出使雷射光進行掃描時之高低差之最大值。此時，使雷射光於突起部12之直徑方向上進行掃描，掃描距離係設定為較突起部12之直徑長之距離。 另一方面，於突起部12之內周面之形狀與突起部12之外周面之形狀(空腔13之外周面之形狀)不同之情形時，例如，於空腔13之外周面為錐台狀之情形時，於氮氣氛圍中，將進入至空腔13中之發熱材30去除。此時，使用刷毛等，一面注意不使空腔13之形狀發生變化一面去除發熱材30。而且，與上述高低差之最大值之測定同樣地，藉由使雷射光進行掃描而測定空腔13之高度尺寸(高度尺寸H2)。 突起部12之形狀並無特別限定，例如成為朝向前端側逐漸變細之形狀。但，突起部12之前端部較佳為成為帶有弧度之形狀。 突起部12之形狀例如可設為圓錐狀、橢圓錐狀或長圓錐狀等錐狀、或者圓錐台狀、橢圓錐台狀或長圓錐台狀等錐台狀。 於本實施形態之情形時，突起部12之形狀形成為圓錐狀。 突起部12之高度尺寸H1(圖4)並無特別限定，例如較佳為2 mm以上且15 mm以下，更佳為3 mm以上且10 mm以下，進而較佳為5 mm以上且8 mm以下。 由於突起部12之高度尺寸H1為2 mm以上且15 mm以下，故而可藉由突起部12充分且適度地按壓生物體之皮膚。 突起部12之直徑並無特別限定，例如較佳為2 mm以上且38 mm以下，更佳為5 mm以上且20 mm以下。由於突起部12之直徑為2 mm以上且38 mm以下，故而可藉由突起部12充分且適度地按壓生物體之皮膚。 突起部12之傾斜角度α(圖4)並無特別限定，例如較佳為30度以上，更佳為45度以上。由於突起部12之傾斜角度α為30度以上，故而可藉由突起部12充分地按壓生物體之皮膚。 又，突起部12之傾斜角度α較佳為80度以下，進而較佳為70度以下，且進一步較佳為65度以下。由於突起部12之傾斜角度α為80度以下，故而可使突起部12相對於生物體之皮膚之陷入情狀為適度之範圍。 再者，如上所述，突起部12之前端部較佳為帶有弧度之形狀。而且，突起部12之前端部之曲率半徑較佳為0.5 mm以上且3.0 mm以下，進而較佳為0.8 mm以上且1.5 mm以下。 此處，例如若為人體之肩部之部分，則筋膜位於距離皮膚之表面約6 mm之深度，較佳為以按壓作用及加溫作用到達該深度之方式，設定突起部12之形狀及發熱材30之發熱性能。又，關於發熱材30之發熱性能，例如較佳為以皮膚之表面之溫度成為37℃以上且44℃以下之方式進行設定，進而較佳為以成為38℃以上且42℃以下之方式進行設定。 複數個突起部12之配置並無特別限定，例如可設為鋸齒格子狀、正方格子狀等配置。 於本實施形態之情形時，例如，如圖2所示，片材10具有呈鋸齒格子狀配置之5個突起部12。更詳細而言，於片材10之中央部配置1個突起部12，於該突起部12之周圍配置剩餘之4個突起部12。該等4個突起部12分別配置於片材10之4個角部。 相鄰之突起部12之中心間距離L(圖2)並無特別限定，較佳為突起部12之高度尺寸H1(圖4)以上，進而較佳為高度尺寸H1之1.5倍以上。藉由如此，可藉由各突起部12充分地按壓生物體之皮膚。 此處，當於在突起部12內未填充有發熱材30之片材10之狀態下，於片材10之面垂直方向上按壓突起部12時，較佳為以對於每個突起部12而言，於1 N之力下突起部12實質上未塑性變形而產生彈性變形之範圍內之突起部12之變形，於25 N之力下突起部12產生塑性變形之方式，設定突起部12之耐負荷性，進而較佳為以對於每個突起部12而言，於5 N之力下突起部12實質上未塑性變形而產生彈性變形之範圍內之突起部12之變形，於18 N之力下突起部12產生塑性變形之方式，設定突起部12之耐負荷性。 藉由如此，可藉由突起部12而充分地按壓生物體之皮膚，並且可使突起部12相對於生物體之皮膚之陷入情狀為適度之範圍。 此處，所謂片材10之面垂直方向係片材10之法線方向(相對於片材10之一面10a正交之方向)。 又，於將在突起部12內填充有發熱材30之本體部50之突起部12在片材10之面垂直方向上進行按壓時，較佳為以對於每個突起部12而言，於3 N之力下突起部12實質上未塑性變形而產生彈性變形之範圍內之突起部12之變形的方式，設定本體部50中與突起部12對應之部位之耐負荷性，進而較佳為以於5 N之力下突起部12亦實質上未塑性變形而產生彈性變形之範圍內之突起部12之變形之方式，設定本體部50中與突起部12對應之部位之耐負荷性。 藉由如此，可藉由突起部12而充分地按壓生物體之皮膚，並且可使突起部12相對於生物體之皮膚之陷入情狀為適度之範圍。 構成本體部50之前後之外表面之片材10與第2片材20中之至少一者具有透氣性。藉此，可通過片材10或第2片材20之至少一者對發熱材30供給氧，而使該發熱材30發熱。 於本實施形態之情形時，例如，片材10具有透氣性，並且片材10之透氣性高於第2片材20之透氣性。 更詳細而言，片材10於突起部12亦具有透氣性，可經由突起部12對發熱材30供給氧，並且可經由突起部12釋出水蒸氣。 更詳細而言，於本實施形態之情形時，第2片材20係例如實質上不使空氣通過之非透氣性之片材。 上述吸水片材40相對於基部11積層於片材10之另一面10b側。 即，溫熱器具100具備相對於片材10之基部11積層於另一面10b側之吸水片材40(圖3)。 由於溫熱器具100具備吸水片材40，故而可利用吸水片材40將發熱材30中之剩餘之水吸收。由此，當將溫熱器具100自包裝材料取出時，可使發熱材30迅速地發熱。 作為吸水片材40，例如可使用包含吸水性聚合物、嫘縈不織布、纖維素不織布或紙等之片材。 其中，吸水片材40較佳為包含吸水性聚合物而構成，此種吸水片材40亦可為藉由使吸水性聚合物成形為片狀而獲得者。 吸水片材40較佳為至少覆蓋各突起部12之後表面側。於此情形時，吸水片材40覆蓋填充於各突起部12內之發熱材30之填充區域之後表面側。由此，可藉由吸水片材40而較佳地吸收填充於各突起部12內之發熱材30中之水分。 再者，於本實施形態中，溫熱器具100亦可代替吸水片材40，而具有非連續地配置(呈非片狀之形狀配置)之吸水性聚合物。 再者，於本實施形態之情形時，發熱材30較佳為實質上不含有吸水性聚合物，藉由如此，可充分地確保發熱材30中之可氧化性金屬之含有比率，故而可充分地確保發熱材30之發熱量及發熱之持續時間。 溫熱器具100具備貼合部60，該貼合部60係用以於突起部12被壓接於皮膚之狀態下將溫熱器具100貼合於生物體。 貼合部60例如具備分別朝一方向(圖2中之左右方向)形成為略微長條之帶狀之一對貼合帶部61而構成。 如上所述，於本實施形態之情形時，本體部50之平面形狀為矩形。例如，沿著本體部50之相互對向之一對緣邊之各者，固定有各貼合帶部61之長度方向上之一端部即基端部66。 貼合帶部61具備片狀之貼合部構成片材63、及形成於貼合部構成片材63之前端側之部分之一面的黏著層64而構成。 黏著層64形成於在貼合部構成片材63中將溫熱器具100貼合於生物體時成為皮膚側之面。 如此，貼合部60係包含黏著固定於皮膚之黏著片材部(例如於貼合部構成片材63中形成有黏著層64之部分)而構成。 因此，藉由於對貼合部60賦予張力之狀態下將黏著片材部黏著固定於皮膚，如圖6所示，可使突起部12壓接於皮膚91，而將溫熱器具100貼合於生物體。 於生物體貼合溫熱器具100之部位並無特別限定。例如可於肩部或脊背等軀幹部、手腕等臂部、腳掌等腳部、眼睛周圍等頭部貼合溫熱器具100。 再者，於溫熱器具100之使用前之狀態下，於各貼合帶部61貼附有覆蓋黏著層64之剝離紙65。 於使用溫熱器具100時，自各貼合帶部61將剝離紙65剝離，將各貼合帶部61之黏著層64貼附於皮膚91，藉此，可將溫熱器具100貼合於生物體。 此處，於本實施形態之情形時，貼合部構成片材63包含可於該貼合部構成片材63之長度方向上伸縮之材料。即，各貼合部構成片材63可於圖2中之箭頭B方向上伸縮。 如此，貼合部60包含伸縮性之伸縮片材部而構成。於本實施形態之情形時，例如，貼合部構成片材63之整體成為伸縮片材部。 於將貼合帶部61在該貼合帶部61之長度方向上拉伸之狀態下，將貼合帶部61之前端部之黏著層64貼附於皮膚91，藉此，可利用更充分之壓接力使突起部12壓接於皮膚91。 以下，對溫熱器具100之各部分之材料及特性之例更詳細地進行說明。 作為發熱材30中之可氧化性金屬，可使用通常被用作此種發熱材之材料之可氧化性金屬。作為該可氧化性金屬，就操作性、成形性等觀點而言，較佳為使用粉體或纖維狀之形態者。 作為具有粉體之形態之可氧化性金屬，例如可列舉鐵粉、鋁粉、鋅粉、錳粉、鎂粉及鈣粉等，該等之中，就操作性及製造成本等方面而言較佳地使用鐵粉。 作為具有粉體之形態之可氧化性金屬，就反應之控制良好之觀點而言，較佳為使用粒徑(以下，於稱作粒徑時係指粉體之形態下之最大長度、或藉由動態光散射法、雷射繞射法等所測定之平均粒徑)為0.1 μm以上且300 μm以下者，更佳為使用含有50質量%以上之粒徑為0.1 μm以上且150 μm以下者。 又，作為具有纖維狀之形態之可氧化性金屬，可列舉鋼纖維、鋁纖維及鎂纖維等。該等之中，就操作性及製造成本等方面而言較佳地使用鋼纖維及鋁纖維等。就發熱性能等方面而言，具有纖維狀之形態之可氧化性金屬較佳為使用纖維長度為0.1 mm以上且50 mm以下，粗度為1 μm以上且1000 μm以下者。 發熱材30中之可氧化性金屬之含量較佳為30質量%以上且80質量%以下，更佳為40質量%以上且70質量%以下。 藉由將該含量設為30質量%以上，可使填充有發熱材30之突起部12之發熱溫度充分地上升至人利用指尖等觸摸後感到熱之程度以上，故較佳。 藉由將該含量設為80質量%以下，發熱材30之透氣性變得充分，其結果，至發熱材30之中心部為止充分地發生反應，而可使發熱材30之發熱溫度充分地上升。又，除可使發熱材30之發熱時間變得充分長以外，亦可使藉由保濕劑所進行之水分供給充分。 此處，發熱材30中之可氧化性金屬之含量可利用依據JIS(Japanese Industrial Standards，日本工業標準)P8128之灰分試驗進行測定，或者，於可氧化性金屬為鐵之情形時，可利用當施加外部磁場時會產生磁化之性質，藉由振動試樣型磁化測定試驗等進行測定。 作為發熱材30中之保濕劑，可使用通常被用作此種發熱材之材料之保濕劑。該保濕劑作為水分保持劑而發揮作用。又，該保濕劑亦可亦具有作為供給劑之功能，該供給劑係保持供給至可氧化性金屬之氧並將該氧供給至可氧化性金屬。 作為該保濕劑，例如較佳地使用無機材料者。 作為該保濕劑，例如較佳地使用多孔質材料。 作為保濕劑，例如可列舉活性碳(椰子殼碳、木炭粉、瀝青炭(bituminous coal)、泥炭、褐炭(lignite))、碳黑、乙炔黑、石墨、沸石、波來鐵、蛭石、二氧化矽、鈣霞石(cancrinite)及螢石等，該等之中，就具有保水能力、氧供給能力及觸媒能力之方面而言，較佳地使用活性碳。 作為該保濕劑，就可形成與可氧化性金屬之有效之接觸狀態之方面而言，較佳為使用粒徑為0.1 μm以上且500 μm以下之粉體狀者，更佳為使用含有50質量%以上之粒徑為0.1 μm以上且200 μm之粉體狀者。 作為該保濕劑，亦可使用除如上所述之粉體狀以外之形態者，例如亦可使用活性碳纖維等纖維狀之形態者。 發熱材30中之保濕劑之含量較佳為1質量%以上且50質量%以下，更佳為2質量%以上且40質量%以下。 藉由將該含量設為1質量%以上，可於發熱材30中充分地蓄積使反應持續至可氧化性金屬藉由氧化反應而溫度上升至人體溫度以上之程度所需之水分。又，由於充分地確保發熱材30之透氣性，故而可充分地進行對發熱材30之氧供給，而可使發熱材30之發熱效率變得良好。 藉由將該含量設為50質量%以下，可抑制發熱材30對於所獲得之發熱量之熱容量，故而發熱溫度上升變大，可獲得人能夠感受到溫熱之溫度上升。 發熱材30亦可含有電解質。 作為該電解質，可使用通常被用作此種發熱材之材料之電解質。 作為該電解質，例如可列舉鹼金屬、鹼土類金屬或重金屬之氯化物或氫氧化物等。而且，該等之中，就導電性、化學穩定性、生產成本優異之方面而言，較佳地使用氯化鈉、氯化鉀、氯化鈣、氯化鎂及氯化鐵(第1、第2)等各種氯化物。該等電解質亦可單獨使用或組合兩種以上而使用。 發熱材30中之電解質之含量以發熱材30中之水質量比計，較佳為0.5質量%以上且24質量%以下，更佳為1質量%以上且10質量%以下。 藉由將該含量設為0.5質量%以上，可使發熱材30之氧化反應充分地進行，且為了確保發熱功能所需之電解質，亦可抑制發熱材30之水分之比率，其結果，可充分地確保發熱溫度上升。 藉由將該含量設為24質量%以下，可使發熱材30之透氣性變得良好，又，為了確保發熱功能所需之電解質，可將發熱材30中之水分比率保持為某種程度之大小，可對可氧化性金屬等供給充分之水，從而使發熱性能優異，且可於發熱材30中均勻地調配電解質，故而較佳。 又，亦可於發熱材30中添加增黏劑或絮凝劑、進而其他添加物。 為了將發熱材30均勻地填充至微細之突起部12之空腔13內，較佳為將該發熱材30以具有流動性之漿料之狀態填充於空腔13內，於此情形時，發熱材30較佳為含有增黏劑。作為增黏劑，主要可使用吸收水分而使稠度增大或賦予觸變性之物質、例如水溶性之高分子材料。 溫熱器具100之突起部12之發熱達到溫度較佳為35℃以上且98℃以下，更佳為38℃以上且70℃以下。 溫熱器具100之發熱達到溫度之測定可利用與JIS S4100相同之方法進行。 關於在突起部12填充有發熱材30之片材10，發熱材30之每單位重量(1 g)於10分鐘內產生之水蒸氣量較佳為20 mg/g以上且250 mg/g以下，更佳為70 mg/g以上且180 mg/g以下。 此處，該水蒸氣量(水蒸氣產生量)係例如以如下方式進行測定。 測定中所使用之裝置具備：鋁製之測定室(容積4.2 L)；流入路徑，其使除濕空氣(濕度未達2%，流量2.1 L/min)流入至測定室之下部；及流出路徑，其使空氣自測定室之上部流出。於流入路徑，安裝有入口溫濕度計及入口流量計。另一方面，於流出路徑，安裝有出口溫濕度計及出口流量計。於測定室內安裝有溫度計(熱敏電阻)。作為溫度計，使用溫度分解能為0.1℃左右者。 於測定環境溫度30℃(30±1℃)下，將溫熱器具100自包裝袋取出，使片材10之一面10a側朝上而載置於測定室，並將附有金屬球(質量4.5 g)之溫度計放置於其上。於該狀態下自測定室之下部流入除濕空氣，基於利用入口溫濕度計及出口溫濕度計所計測之溫度及濕度，求出空氣流入至測定室之前後之絕對濕度之差。進而，基於利用入口流量計及出口流量計所計測之流量，算出溫熱器具100所釋出之水蒸氣量。計測自測定開始經過10分鐘為止之水蒸氣產生量。

較佳為，不織布片材15中之第1樹脂材料之含量為60質量%以上且95質量%以下。又，不織布片材15中之第2樹脂材料之含量為5質量%以上且40質量%以下。 藉由如此設定不織布片材15中之第1樹脂材料及第2樹脂材料之含量，可充分地確保不織布片材15之透氣性，且可充分地確保不織布片材15之剛性。 不織布片材15之基重為15 g/m² 以上且500 g/m² 以下，尤佳為30 g/m² 以上且350 g/m² 以下。由於不織布片材15之基重為15 g/m² 以上，故而可確保片材10之充分之強度，此外，可使發熱材30之溫度適度地緩和後傳遞至皮膚。由於不織布片材15之基重為500 g/m² 以下，故而可經由片材10將發熱材30之溫度有效率地傳遞至皮膚。 片材10之基部11之厚度為0.03 mm以上且2.6 mm以下，尤佳為0.08 mm以上且1.25 mm以下。由於基部11之厚度為0.03 mm以上，故而片材10之形態保持性(尤其是突起部12之形態保持性)、進而本體部50之形態保持性良好。由於基部11之厚度為2.6 mm以下，故而片材10之傳熱性良好。 片材10之透濕度例如較佳為1000 g/(m² ∙24 h)以上且17000 g/(m² ∙24 h)以下，更佳為2000 g/(m² ∙24 h)以上且12000 g/(m² ∙24 h)以下。

第2片材20之基重較佳為10 g/m² 以上且200 g/m² 以下，且20 g/m² 以上且100 g/m² 以下。藉由將第2片材20之基重設定為此種範圍，可利用第2片材20限制伴隨發熱之水蒸氣之產生方向。 作為第2片材20，可列舉包含樹脂膜之片材，該樹脂膜包含聚乙烯、聚丙烯等聚烯烴；及聚酯、聚醯胺、聚胺基甲酸酯、聚苯乙烯、尼龍、聚偏二氯乙烯、聚乙烯-乙酸乙烯酯共聚物等樹脂，尤其是，藉由使用於上述樹脂中調配有氧化鈦等無機填料之片材，利用第2片材20所得之發熱材30之隱蔽性變得良好。第2片材20亦可將複數片重疊而使用。 更詳細而言，作為第2片材20，例如可列舉紙與上述樹脂膜之積層片材、或不織布與上述樹脂膜之積層片材。於此情形時，樹脂膜成為第2片材20之內表面側(吸水片材40側)，構成第2片材20之紙或不織布配置於第2片材20之外表面側(後表面側)。進而，為了抑制朝背面側之散熱，亦可於第2片材20之後表面側積層不織布。

mm以上且1 mm以下。 由於吸水片材40之厚度為0.05 mm以上，故而可藉由吸水片材40而充分地吸收水分。又，由於吸水片材40之厚度為2 mm以下，故而可使本體部50充分地構成為薄型。 吸水片材40之厚度之測定例如可藉由孔雀牌厚度計(PEACOCK GAUGE)測定法而進行。 作為吸水片材40，使用可實現水分之吸收保持且具有柔軟性之薄片材料。作為此種薄片材料，例如可列舉以纖維為原料之紙、不織布、梭織物、編織物等纖維片材、或海綿等多孔體等。作為成為吸水片材40之材料之纖維，例如可列舉以植物纖維或動物纖維等天然纖維為主成分之纖維或以化學纖維為主成分之纖維。作為植物纖維，例如可列舉選自棉花(cotton)、木棉(kapok)、木漿、非木漿、花生蛋白纖維、玉米蛋白纖維、大豆蛋白纖維、甘露聚醣纖維、橡膠纖維、麻、馬尼拉麻、瓊麻、紐西蘭麻、羅布麻、椰子纖維、燈心草及麥稈中之1種或2種以上。作為動物纖維，例如可列舉選自羊毛、山羊毛、馬海毛、開司米山羊毛、阿爾帕卡毛、安哥拉兔毛、駝毛、駱馬毛、蠶絲、羽毛、絨毛、翎毛、海藻纖維、幾丁質纖維及酪蛋白纖維中之1種或2種以上。作為化學纖維，例如可使用選自嫘縈、乙酸纖維及纖維素中之1種或2種以上。

其中較佳之形態為(ii)之形態。再者，(ii)之形態之吸水片材40例如可於包含成分(a)之片材上均勻地散佈成分(b)之吸水性聚合物，且自其上噴灑200 g/m² 之量之水之後，進而於其上積層包含成分(a)之相同或互不相同之片材，於100±0.5℃下，以5 kg/ cm² 之壓力進行加壓乾燥，乾燥至含水率成為5質量%以下為止而進行製造。 作為吸水性聚合物，藉由使用可吸收及保持自重之20倍以上之液體且可凝膠化之水凝膠材料，可確保吸水片材40之充分之吸水性能。作為吸水性聚合物之粒子之形狀，可列舉球狀、塊狀、葡萄串狀及纖維狀等。吸水性聚合物之粒子之粒徑較佳為1 μm以上，進而較佳為10 μm以上。又，吸水性聚合物之粒子之粒徑較佳為1000 μm以下，進而較佳為500

成分(b)吸水性聚合物之粒子於吸水片材40中所占之比率於乾燥狀態下較佳為10質量%以上，進而較佳為20質量%以上。又，成分(b)吸水性聚合物之粒子於吸水片材40中所占之比率於乾燥狀態下較佳為70質量%以下，進而較佳為65質量%以下。 吸水片材40於乾燥狀態下其基重較佳為20 g/m² 以上且250 g/m² 以下，進而較佳為40 g/m² 以上且220 g/m² 以下，且進而較佳為60 g/m²

其次，對本實施形態之溫熱器具之製造方法進行說明。 本實施形態之溫熱器具之製造方法具備如下步驟：藉由衝壓而於片材10形成突起部12；及於突起部12之空腔13填充發熱材30。 為了於片材10形成突起部12，首先，準備成為不織布片材15之原料之不織布片材18。 此處，不織布片材18例如包含如下而構成，即，包含第1樹脂材料之第1纖維、及包含第2樹脂材料之第2纖維(第1纖維與第2纖維之混棉之情形)。但，構成不織布片材18之纖維亦可成為芯鞘構造，該芯鞘構造包含：包含第1樹脂材料之芯，及包含第2樹脂材料之鞘。 其次，藉由對不織布片材18進行熱壓，而成形形成有突起部12之片材10。 此處，熱壓之溫度係設定為第1樹脂材料之熔點與第2樹脂材料之熔點之中間之溫度。即，熱壓之溫度設為未達第1樹脂材料之熔點之溫度且第2樹脂材料之熔點以上之溫度。 藉此，可使得第2樹脂材料熔融，另一方面，第1樹脂材料不熔融，故而經由熔融之第2樹脂材料，包含第1樹脂材料之纖維(該纖維亦可為芯鞘構造之芯之部分)彼此黏結。即，熔融之第2樹脂材料構成將包含第1樹脂材料之纖維彼此黏結之黏結部。 其結果，可確保片材10之透氣性，且可充分地確保片材10之剛性。即，可充分地確保基部11之透氣性及剛性，並且對於突起部12，亦可自該突起部12之基端遍及前端，一面確保透氣性，一面使整體為充分之剛性。 此處，熱壓之溫度較佳為設定為於第2樹脂材料可充分地熔融之範圍內儘可能低溫(例如，第2樹脂材料之熔點+30℃以下之溫度，較佳為第2樹脂材料之熔點+20℃以下之溫度)。藉由如此，可使熱壓後之不織布片材15具有不織布之質感，本體部50之肌膚觸感變得良好。 此處，例如，如圖5(a)所示，可使用相互對向地配置之第1模具70及第2模具80而於片材10形成突起部12。 第1模具70具備：平坦面71，其與第2模具80對向；及複數個突起部72，其等自平坦面71朝第2模具80側突出。 第2模具80具備：平坦面81，其與第1模具70對向；及複數個凹部82，其等於平坦面81中分別形成於與各突起部72對向之部位。 如圖5(b)所示，使第1模具70與第2模具80相互近接且將片材10於厚度方向上進行加壓，並且藉由第1模具70及第2模具80將片材10進行加熱，藉此於片材10形成複數個突起部12。於片材10中，與第1模具70及第2模具80之平坦面71、81對應之部位成為基部11，與第1模具70及第2模具80之突起部72及凹部82對應之部位成為突起部12。 如此於片材10形成突起部12之後，於突起部12填充發熱材30。 為此，製備包含可氧化性金屬、保濕劑及水之發熱材30之原料組合物(漿料)，使該原料組合物流入至各突起部12。 藉此，可按照突起部12之內周面之形狀填充發熱材30。由此，發熱材30之形狀例如可設為與突起部12之形狀相同之錐狀或錐台狀之形狀。 於在片材10之各突起部12填充發熱材30之後，於片材10之基部11上積層吸水片材40。 進而，於吸水片材40上積層第2片材20，並將第2片材20之周緣部與片材10之周緣部相互接合。 第2片材20與片材10之接合既可使用接著劑進行，亦可藉由熱密封而進行。 如此，可製作本體部50。 其次，將一對貼合帶部61之基端部66分別接合於本體部50。 貼合帶部61對於本體部50之接合既可使用接著劑進行，亦可藉由熱密封而進行。 如此，製造出溫熱器具100。 根據如上所述之第1實施形態，溫熱器具100具備：片材10，其具有向一面10a側凸狀彎曲且另一面10b側成為空腔13之突起部12；及發熱材30，其被填充於突起部12之空腔13。 因此，藉由以突起部12被壓接於皮膚之狀態將溫熱器具100貼合於人體等生物體，可一面利用突起部12按壓生物體之皮膚，一面將生物體之皮膚中與突起部12對應之部位局部充分地溫熱。 又，如上所述，溫熱器具100具備突起部12，並且發熱材30包含可氧化性金屬、保濕劑及水而構成，故而可不使用針或火，而藉由突起部12將生物體一面局部地進行按壓一面加溫。 又，溫熱器具100具備貼合部60，該貼合部60係用以於突起部12被壓接於皮膚之狀態下將該溫熱器具100貼合於生物體，故而可容易地將溫熱器具100貼合於生物體，並且例如可一面進行看電視或做家務等其他事，一面進行生物體之局部之按壓與加溫。 其次，使用圖7(a)至圖7(k)，對片材10之平面形狀、突起部12之配置及突起部12之形狀之變化例進行說明。 ＜變化例1＞

再者，第1突起部12a之高度尺寸例如與第2突起部12b之高度尺寸相等。因此，第1突起部12a之傾斜角度較第2突起部12b之傾斜角度平緩。即，就第1突起部12a與第2突起部12b而言，形狀互不相同。 又，於本變化例之情形時，片材10及本體部50之平面形狀例如成為圓形。 但，第1突起部12a之高度尺寸亦可大於第2突起部12b之高度尺寸，藉由如此，可藉由中央之第1突起部12a更充分地按壓生物體之皮膚。 又，第2突起部12b之高度尺寸亦可大於第1突起部12a之高度尺寸，藉由如此，可藉由周圍之第2突起部12b更充分地按壓生物體之皮膚。 ＜變化例4＞ 圖7(g)及圖7(h)係用以說明片材10之平面形狀及突起部12之配置之變化例4之圖，其中圖7(g)係俯視圖，圖7(h)係沿著圖7(g)之A-A線之剖視圖。

又，於本變化例之情形時，片材10具有尺寸互不相同之複數種突起部12。 更詳細而言，於本變化例之情形時，片材10及本體部50之平面形狀例如與變化例1及2相同。而且，於片材10之中央部配置有橫向之長圓形之1個突起部12(以下為第1突起部12a)，於第1突起部12a之周圍配置有複數個(例如8個)突起部12(以下為第2突起部12b)。 第1突起部12a之頂部具有橫向之稜線(參照圖7(j))。 本變化例之片材10中之第1突起部12a之配置區域相當於變化例1及2之片材10中之中央部之2個突起部12之配置區域。即，第1突起部12a之尺寸與第2突起部12b之尺寸互不相同，例如，於在片材10之面垂直方向上觀察時，第1突起部12a之外形尺寸大於第2突起部12b之外形尺寸。 第1突起部12a之平面形狀例如成為長圓形。另一方面，第2突起部12b之平面形狀例如成為圓形。即，就第1突起部12a與第2突起部12b而言，形狀互不相同。 ＜變化例6＞ 圖7(k)係用以說明片材10之平面形狀及突起部12之配置之變化例6之圖。於本變化例之情形時，複數個(例如4個)突起部12呈直線狀排列配置。 [第2實施形態] 其次，使用圖8至圖9(b)說明第2實施形態。 本實施形態之溫熱器具100與上述第1實施形態之溫熱器具100之不同點在於片材10之構成，就其他方面而言，構成為與上述第1實施形態之溫熱器具100相同。 於上述第1實施形態中，說明了片材10包含1片不織布片材15之例。 與此相對，於本實施形態中，片材10包含以下部分而構成，即：不織布片材15(第1不織布片材)，其構成該片材10中之一最外層；不織布片材17(第2不織布片材)，其構成該片材10中之另一最外層；及透氣片材16，其構成位於第1不織布片材與第2不織布片材之間之中間層。 更詳細而言，於本實施形態之情形時，片材10例如如圖8所示，成為不織布片材15、透氣片材16及不織布片材17之3層構造。 但，本發明並不限定於該例，片材10亦可包含不織布片材15、透氣片材16及不織布片材17之3層其他層而構成。作為一例，片材10亦可於不織布片材15與不織布片材17之間具備2層透氣片材16，進而，於該等2層透氣片材16彼此之間具備第3不織布片材，而成為合計5層之層構造。 如上述第1實施形態中所作說明般，不織布片材15包含以下部分而構成，即：纖維，其包含第1樹脂材料；及黏結部，其包含第2樹脂材料且將纖維彼此黏結。又，不織布片材17亦與不織布片材15同樣地包含以下部分而構成，即：纖維，其包含第1樹脂材料；及黏結部，其包含第2樹脂材料且將纖維彼此黏結。 即，第1不織布片材及第2不織布片材之各者包含以下部分而構成，即：纖維，其包含第1樹脂材料；及黏結部，其包含第2樹脂材料且將纖維彼此黏結。 但，構成不織布片材15之第1樹脂材料與構成不織布片材17之第1樹脂材料既可為相互相同之材料，亦可為互不相同之材料。 又，構成不織布片材15之第2樹脂材料與構成不織布片材17之第2樹脂材料既可為相互相同之材料，亦可為互不相同之材料。

再者，於本實施形態之情形時，構成不織布片材15之纖維亦可成為芯鞘構造，該芯鞘構造包含：包含第1樹脂材料之芯，及包含第2樹脂材料之鞘。 又，關於構成不織布片材17之纖維，亦可同樣地成為芯鞘構造，該芯鞘構造包含：包含第1樹脂材料之芯，及包含第2樹脂材料之鞘。 透氣片材16包含熔點較第2樹脂材料高之第3樹脂材料而構成。 透氣片材16之透氣性並無特別限定，例如，透氣片材16之透濕度較佳為100 g/(m² ∙24 h)以上且13000 g/(m² ∙24 h)以下，尤佳為200 g/(m² ∙24 h)以上且8000 g/(m² ∙24 h)以下。藉由將透氣片材16之透濕度設定為此種範圍，當自包裝材料取出溫熱器具100時，可使氧迅速地通過片材10而供給至發熱材30，而可自該發熱材30迅速地產生熱及水蒸氣，並且可使發熱之持續時間充分長。透氣片材16之透濕度之測定例如可利用JIS(Z0208) CaCl₂ 法進行，測定條件可設為40℃、90%RH。 透氣片材16可遍及其整個面具有透氣性，亦可局部地具有透氣性。 透氣片材16之基重較佳為10 g/m² 以上且200 g/m² 以下，尤佳為20 g/m² 以上且100 g/m² 以下。藉由將透氣片材16之基重設定為此種範圍，當自包裝材料取出溫熱器具100時，可迅速地產生熱及水蒸氣，並且可使發熱之持續時間充分長。 作為透氣片材16，可列舉如下片材等：於包含聚乙烯、聚丙烯等聚烯烴或聚酯、聚醯胺、聚胺基甲酸酯、聚苯乙烯、聚乙烯-乙酸乙烯酯共聚物等樹脂之片材機械地形成有透氣孔者；藉由延伸而使該等樹脂與無機填料之混合片材界面剝離從而設置有微細之透氣孔者；或利用其結晶構造之界面剝離而形成有微細之透氣孔者；以及利用發泡成形之連續起泡使微細之透氣孔連通而得者。又，作為透氣片材16，亦可列舉由聚烯烴等合成紙漿、木漿、嫘縈、乙酸纖維等半合成纖維、維尼綸纖維、聚酯纖維等形成之不織布、織布、合成紙及紙等。透氣片材16亦可使複數片重疊而使用。 更詳細而言，作為透氣片材16，藉由延伸而使聚丙烯與碳酸鈣之混合片材界面剝離，藉此，可較佳地使用在該混合片材形成有微細之透氣孔者。 於本實施形態中，藉由使聚丙烯與碳酸鈣之混合片材延伸而構成透氣片材16，並進行以下說明。 其次，對本實施形態之溫熱器具之製造方法進行說明。 本實施形態之溫熱器具之製造方法亦具備如下步驟：藉由衝壓而於片材10形成突起部12；及於突起部12之空腔13填充發熱材30。 為了於片材10形成突起部12，首先，準備成為不織布片材15之原料之不織布片材18、透氣片材16、及成為不織布片材17之原料之不織布片材19，以依照不織布片材18、透氣片材16及不織布片材19之順序重疊之方式將該等3片片材積層。 如上所述，不織布片材18例如包含以下部分而構成，即：第1纖維，其包含第1樹脂材料；及第2纖維，其包含第2樹脂材料。但，構成不織布片材18之纖維亦可成為芯鞘構造，該芯鞘構造包含：包含第1樹脂材料之芯，及包含第2樹脂材料之鞘。 不織布片材19亦為例如與不織布片材18相同者。 其次，藉由對該等3片片材(不織布片材18、透氣片材16及不織布片材19)之積層體進行熱壓，而成形形成有突起部12之片材10(參照圖9(a)、圖9(b))。 於本實施形態中，熱壓之溫度亦設定為第1樹脂材料之熔點與第2樹脂材料之熔點之中間之溫度。即，熱壓之溫度設為未達第1樹脂材料之熔點之溫度且第2樹脂材料之熔點以上之溫度。 藉此，可使得第2樹脂材料熔融，另一方面，使第1樹脂材料不熔融，故而經由熔融之第2樹脂材料，包含第1樹脂材料之纖維(該纖維亦可為芯鞘構造之芯之部分)彼此黏結。即，熔融之第2樹脂材料構成將包含第1樹脂材料之纖維彼此黏結之黏結部。 由此，可確保不織布片材15及不織布片材17之透氣性，且可充分地確保不織布片材15及不織布片材17之剛性，故而可充分地確保片材10之透氣性及剛性。即，可充分地確保基部11之透氣性及剛性，並且對於突起部12，亦可自該突起部12之基端遍及前端，一面確保透氣性，一面使整體為充分之剛性。 於本實施形態之情形時，熱壓之溫度亦較佳為設定為於第2樹脂材料可充分地熔融之範圍內儘可能低溫(例如，第2樹脂材料之熔點+30℃以下之溫度，較佳為第2樹脂材料之熔點+10℃以下之溫度)。藉由如此，可使熱壓後之不織布片材15及不織布片材17具有不織布之質感。尤其是，藉由使位於本體部50之外表面側之不織布片材17具有不織布之質感，本體部50之肌膚觸感變得良好。 於本實施形態之情形時，熱壓之溫度較佳為設定為較透氣片材16所包含之第3樹脂材料之熔點低之溫度且較透氣片材16之延伸溫度低之溫度。藉此，於熱壓後亦可維持透氣片材16之透氣孔，從而確保該透氣片材16之透氣性。 如此，於本實施形態之溫熱器具之製造方法中，片材包含以下部分而構成，即：不織布片材18(第1不織布片材)，其構成該片材中之一最外層；不織布片材19(第2不織布片材)，其構成該片材中之另一最外層；及透氣片材16，其構成位於第1不織布片材與第2不織布片材之間之中間層；且第1不織布片材及第2不織布片材之各者包含以下部分而構成，即：纖維，其包含第1樹脂材料；及第2樹脂材料，其熔點較第1樹脂材料低；且透氣片材16包含熔點較第2樹脂材料高之第3樹脂材料而構成。 而且，於藉由衝壓在片材形成突起部12之步驟中，於第2樹脂材料之熔點與第3樹脂材料之熔點之中間之溫度下將片材進行熱壓。 如此，於本實施形態中，於在包含第3樹脂材料而構成之透氣片材16之兩面分別重疊有不織布片材18與不織布片材19之狀態下，將該等3層片材(不織布片材18、透氣片材16及不織布片材19)進行熱壓，藉此形成突起部12。 藉此，於熱壓時，可分別藉由不織布片材18、19而保護透氣片材16之兩面。因此，即便於供熱壓之片材10所具備之透氣片材16包含例如如聚丙烯等之具有較高之結晶性之第3樹脂材料之情形時，亦可一面抑制透氣片材16之斷裂，一面於片材10形成突起部12。由此，可使片材10遍及整個面具有均勻之透氣性。 又，熱壓後之片材10成為於透氣片材16之兩面分別配置有不織布片材15、17之積層構造。因此，可更容易地確保片材10之剛性，尤其是對於突起部12亦可良好地確保剛性。 再者，於熱壓後之片材10中，不織布片材15之第2樹脂材料及不織布片材17之第2樹脂材料既可黏結於透氣片材16，亦可不黏結於透氣片材16。 於本實施形態之情形時，不織布片材15之第2樹脂材料及不織布片材17之第2樹脂材料未黏結於透氣片材16，藉此，可良好地維持透氣片材16之透氣性。 於片材10形成突起部12之後之製造步驟與第1實施形態相同，故而省略說明。 如此，製造出本實施形態之溫熱器具100。 根據第2實施形態，片材10包含以下部分而構成，即：不織布片材15(第1不織布片材)，其構成該片材10中之一最外層；不織布片材17(第2不織布片材)，其構成該片材10中之另一最外層；及透氣片材16，其構成位於第1不織布片材與第2不織布片材之間之中間層。藉此，可更容易地確保片材10之剛性，尤其是對於突起部12亦可良好地確保剛性，可藉由突起部12而更充分地按壓生物體之皮膚。 又，透氣片材16包含第3樹脂材料而構成，第3樹脂材料之熔點高於構成不織布片材15、17之第2樹脂材料之熔點，故而可容易地獲得良好地維持透氣片材16之透氣性之構造之溫熱器具100。 再者，於第2實施形態中，主要對使用藉由使聚丙烯與碳酸鈣之混合片材延伸而構成者作為透氣片材16之例進行了說明，但本發明並不限於該例。例如，透氣片材16亦可為藉由於包含第3樹脂材料之樹脂片材形成複數個細孔而製作者。即，透氣片材16例如為包含第3樹脂材料之樹脂片材，且具有貫通該透氣片材16之正背之複數個細孔。 再者，亦較佳為，於在上述熱壓時在透氣片材16之兩面重疊不織布片材18與不織布片材19之前，預先使不織布貼合於透氣片材16，而補強透氣片材16。 [第3實施形態] 其次，使用圖10說明第3實施形態。 本實施形態之溫熱器具100於以下所說明之方面與上述第1實施形態或第2實施形態之溫熱器具100不同，就其他方面而言，構成為與上述第1實施形態或第2實施形態之溫熱器具100相同。 於本實施形態之情形時，溫熱器具100構成為分別具備以下所說明之貼合部60及本體部50。於本實施形態之情形時，貼合部60與本體部50最初如圖10所示般分離。例如，於使用時等，使用者可藉由將本體部50安裝於貼合部60而使用溫熱器具100。 貼合部60具備一對貼合帶部61、及安裝有該等貼合帶部61之基底片材111。基底片材111之平面形狀例如與本體部50之平面形狀相同。一對貼合帶部61之每一者分別安裝於基底片材111之兩端部，藉此，一對貼合帶部61經由基底片材111而相互連結。 基底片材111之材料並無特別限定。基底片材111例如既可為不織布片材，亦可為樹脂片材。不管基底片材111有無透氣性。 本體部50例如具備黏著層112，該黏著層112形成於第2片材20中成為本體部50之外表面側之面。再者，於溫熱器具100之使用前之狀態下，於黏著層112貼附有與上述剝離紙65相同之剝離紙，該黏著層112被該剝離紙覆蓋。 於使用溫熱器具100時，將該剝離紙自黏著層112剝離，並將黏著層112貼附於基底片材111，藉此將本體部50安裝於貼合部60。其後，可如第1實施形態中所作說明般將溫熱器具100貼合於生物體，且使突起部12壓接於生物體之皮膚。 於本實施形態之情形時，本體部50與第1實施形態及第2實施形態同樣地具有複數個突起部12。即，本體部50係包含複數個突起部12及分別填充於該等突起部12之空腔13之發熱材30而構成之突起部單元。 再者，亦較佳為可對基底片材111反覆貼合及剝離黏著層112。藉由如此，可將本體部50拋棄，另一方面，可針對1個貼合部60將複數個本體部50依序貼附及剝離，而反覆使用貼合部60。 再者，亦可為藉由面扣結件而使本體部50可裝卸於貼合部60。 [第4實施形態] 其次，使用圖11(a)至圖12(b)說明第4實施形態。 本實施形態之溫熱器具100於以下所說明之方面與上述第3實施形態之溫熱器具100不同，就其他方面而言，構成為與上述第3實施形態之溫熱器具100相同。 於本實施形態之情形時，溫熱器具100亦可代替上述貼合部60而具備以下所說明之貼合具114(貼合部)(圖11(b))。 如圖11(b)所示，貼合具114例如可列舉由可彈性變形之樹脂材料一體成形，但並不限定於一體成形之構成。貼合具114具備：一對對向部115，其等相互對向而配置；及連結部116，其將該等對向部115彼此相互連結。一對對向部115之各者形成為板狀。又，例如，連結部116亦形成為板狀。因此，貼合具114總體上成為如使於一方向上為長條之板呈U字狀彎曲之形狀。 貼合具114可朝一對對向部115之對向間隔擴大之方向彈性變形。於一對對向部115之對向間隔被擴大之狀態下，貼合具114欲彈性恢復(彈性復原)為最初之形態，藉此，貼合具114具有朝一對對向部115之對向間隔變窄之方向之施壓力。 於一對對向部115之各者之前端，例如形成有彎曲部117。一對向部115之前端之彎曲部117朝遠離另一對向部115之方向彎曲。同樣地，另一對向部115之彎曲部117朝遠離一對向部115之方向彎曲。 但，貼合具114亦可不具備彎曲部117。 例如，於一對對向部115中，於相互對向之面形成有複數個肋118。該等複數個肋118例如相互平行地延伸。 但，貼合具114亦可不具備肋118。 於本實施形態之情形時，如圖11(a)所示，本體部50於一方向上形成為長條。例如，複數個突起部12排列成一行而配置。 於本實施形態之情形時，本體部50亦具備與第3實施形態相同之黏著層112(參照圖12(b))。又，於溫熱器具100之使用前之狀態下，於黏著層112貼附有剝離紙。 於使用溫熱器具100時，自黏著層112將剝離紙剝離，並將黏著層112貼附於貼合具114之內表面，藉此，將本體部50安裝於貼合具114。 於該狀態下，突起部12較佳為配置於與對向部115對應之位置，另一方面，未配置於與連結部116對應之位置(參照圖12(b))。 於將本體部50安裝於貼合具114之狀態下，使一對對向部115之對向間隔擴大，進而，於該狀態下，將手掌113等***至一對對向部115之對向間隔，解除將一對對向部115之對向間隔擴大之力。 藉此，貼合具114彈性恢復，故而例如如圖12(a)及圖12(b)所示，可使突起部12壓接於手掌113中大拇指與食指之間之部分之皮膚，並利用突起部12按壓位於該部分之穴位等。 如此，於本實施形態之情形時，貼合部係如下之貼合具114，即，介隔突起部12利用彈性復原力夾持生物體之一部分(手掌113等)，藉此使突起部12壓接於皮膚。 再者，貼合具114亦可為與溫熱器具100分開地提供，並與溫熱器具100組合而使用者。於此情形時，例如，本體部50本身成為溫熱器具100。 即，本實施形態之貼合具114係用以將具有突起部12之溫熱器具100貼合於生物體之貼合具114，藉由介隔突起部12利用彈性復原力夾持生物體之一部分，而使突起部12壓接於皮膚。 根據本實施形態之貼合具114，可將具有突起部12之溫熱器具100貼合於生物體，並且可藉由貼合具114之彈性復原力而使突起部12壓接於生物體之皮膚。由此，可藉由簡單之構成之貼合具114，使突起部12持續地壓接於皮膚。 又，如上所述，該貼合具具備：一對對向部115，其等相互對向地配置；及連結部116，其將該等對向部115彼此相互連結；且可於一對對向部115之對向間隔擴大之方向上彈性變形。 此處，貼合具114具備複數個肋118，故而可將本體部50更穩定地安裝於貼合具114，且可抑制本體部50相對於貼合具114之位置偏移。 又，貼合具114具備彎曲部117，故而於為了將貼合具114自手掌113等卸除而欲使一對對向部115之對向間隔擴大時，可將手指卡於彎曲部117而容易地將一對對向部115之對向間隔擴大。 再者，於本實施形態中，說明了本體部50藉由黏著層112而貼附於貼合具114之例，亦可僅藉由貼合具114之彈性復原力而將本體部50夾入至貼合具114與皮膚之間。 [第5實施形態] 其次，使用圖13說明第5實施形態。 本實施形態之溫熱器具100於以下所說明之方面與上述第3實施形態之溫熱器具100不同，就其他方面而言，構成為與上述第3實施形態之溫熱器具100相同。 於本實施形態之情形時，溫熱器具100僅由本體部50構成，不具備貼合部60(或貼合具114)。 又，本體部50所具備之突起部12之數量並無特別限定，例如如圖13所示，本體部50所具備之突起部12之數量可設為1個。 作為使用本實施形態之溫熱器具100之方法，除將溫熱器具100之黏著層112貼附於如圖10所示之貼合部60而使用之方法及將溫熱器具100之黏著層112貼附於如圖11(b)所示之貼合具114而使用之方法以外，例如亦可列舉於將黏著層112貼附於手之指尖之狀態下，利用手指將突起部12壓抵於皮膚而使用之方法等。 [第6實施形態] 其次，使用圖14(a)至圖15(c)說明第6實施形態。 本實施形態之溫熱器具100於以下所說明之方面與上述第4實施形態之溫熱器具100不同，就其他方面而言，構成為與上述第4實施形態之溫熱器具100相同。 於本實施形態之情形時，例如如圖14(a)或圖14(b)所示，本體部50所具有之突起部12之數量成為2個(圖14(a))或1個(圖14(b))。本體部50具有片狀之部分、及自該片狀之部分朝一方突出之突起部12。 該片狀之部分之平面形狀並無特別限定，例如形成為矩形(較佳為圓角之矩形)。 於本實施形態之情形時，於貼合具114之一對對向部115中之一對向部115(以下為對向部115a)，形成有可供插拔本體部50之保持槽181。 保持槽181例如包含以下部分而構成，即：一對側方槽部181a，其等分別配置於對向部115a之寬度方向上之兩端；及連結槽部181b，其將一對側方槽部181a彼此連結。對向部115a之寬度方向係圖15(c)中之左右方向，且係圖15(b)中之紙面之裡側方向及近前側方向。一對側方槽部181a之各者例如自連結部116側朝向對向部115之前端側呈直線狀延伸。連結槽部181b配置於一對側方槽部181a之連結部116側之端部彼此之間，將該等端部彼此相互連接。連結槽部181b係於對向部115a之寬度方向上延伸。 一對側方槽部181a之各者朝向相互之方向打開。連結槽部181b朝向對向部115a之前端側打開。 對向部115a具備平板狀之板狀部182及保持爪部183而構成，該保持爪部183係以該板狀部182為基準配置於另一對向部115(以下為對向部115b)側。 保持爪部183與板狀部182之間之空間(間隙)構成保持槽181。 保持爪部183包含以下部分而構成，即：一對側方爪部183a，其等分別配置於對向部115a之寬度方向上之兩端；及連結爪部183b，其將一對側方爪部183a彼此連結。一對側方爪部183a之各者例如自對向部115a之連結部116側之部分朝向對向部115之前端側呈直線狀延伸。連結爪部183b配置於一對側方爪部183a之連結部116側之端部彼此之間，將該等端部彼此相互連接。 於與對向部115a之前基端方向正交之剖面中，側方爪部183a之形狀成為L字狀(參照圖15(c))。 於與對向部115a之寬度方向正交之剖面中，連結爪部183b之形狀成為L字狀(圖示省略)。 保持爪部183係於與另一對向部115b對向之位置具有U字狀之切口形狀部。 板狀部182之厚度方向上之保持槽181之尺寸被設定為與本體部50之片狀之部分之厚度尺寸相等，或略微大於該片狀之部分之厚度尺寸之程度。 於本實施形態之情形時，本體部50不具有黏著層112。 於本實施形態之情形時，可如以下所作說明般將本體部50貼合於對向部115a。 首先，使本體部50之片狀之部分自對向部115a之前端側朝圖15(b)中之箭頭A方向相對於對向部115a相對地移動。藉此，將該片狀之部分之相互對向之一對緣邊部53(參照圖14(a)、圖14(b))分別***至一對側方槽部181a，將連接該等緣邊部53之一端彼此之另一緣邊部***至連結槽部181b。此時，一對緣邊部53相對於一對側方槽部181a滑動。 如此，如圖15(a)至圖15(c)所示，可使本體部50成為貼合於對向部115a之狀態。於該狀態下，本體部50之突起部12係經由保持爪部183之U字狀之切口形狀部而朝向另一對向部115b側突出。 又，使貼合於對向部115a之本體部50朝圖15(b)中之箭頭B方向，相對於對向部115a相對地移動，藉此，可將本體部50自對向部115a拔出。此時，一對緣邊部53亦相對於一對側方槽部181a滑動。 例如，於另一對向部115b中，於與一對向部115a對向之面形成有朝向對向部115a側突出之突起部185。 又，於一對向部115a中，於與另一對向部115b側為相反側之面1151，例如設置有突起部186。 但，本發明並不限定於該例，亦可為於對向部115b未形成有突起部185。又，亦可為於對向部115a未設置有突起部186。 此處，說明了一對對向部115中之一對向部115a具有用以保持本體部50之構造(保持槽181及保持爪部183)之例，但亦可為一對對向部115之兩者具有保持槽181及保持爪部183。 於本實施形態之情形時，亦與第4實施形態同樣地，貼合具114亦可為與溫熱器具100分開地提供，並與溫熱器具100組合而使用者，於此情形時，例如本體部50本身成為溫熱器具100。 如此，一對對向部115之至少一者具有保持溫熱器具100之保持部(例如包含保持槽181及保持爪部183)。 又，保持部將片狀之溫熱器具100之相互對向之一對緣邊部53分別可裝卸地保持。 又，保持部具有一對槽部(一對側方槽部181a)，該一對槽部(一對側方槽部181a)可藉由供溫熱器具100之一對緣邊部53分別滑動而供其等插拔。 本發明並不限定於上述各實施形態及各變化例，亦包含可達成本發明之目的之範圍內之各種變形、改良等態樣。 例如，發熱材30亦可包含可氧化性金屬、保濕劑、水及吸水性聚合物而構成。 由於發熱材30包含吸水性聚合物而構成，故而可利用吸水性聚合物將發熱材30中之剩餘之水吸收。由此，當將溫熱器具100自包裝材料取出時，可使發熱材30迅速地發熱。 於發熱材30包含吸水性聚合物而構成之情形時，溫熱器具100亦可不具備上述吸水片材40(圖3)。 發熱材30中之吸水性聚合物之含量較佳為1質量%以上且12質量%以下，更佳為2質量%以上且8質量%以下。藉由將發熱材30中之吸水性聚合物之含量設為1質量%以上，可利用吸水性聚合物充分地吸收水分。又，藉由將發熱材30中之吸水性聚合物之含量設為12質量%以下，可充分地確保有助於發熱之可氧化性金屬之發熱材30中之含量。 又，於上述實施形態中，對貼合部60具備黏著性之一對貼合帶部61而構成之例進行了說明，但本發明並不限定於該例，例如亦可使用包袋等帶狀體將本體部50纏繞於腳或手臂等，而使突起部12壓接於皮膚。 又，貼合部60亦可為如具備掛於使用者之耳部之一對掛耳部之眼罩的形態。即，貼合部60亦可代替一對貼合帶部61而具備一對掛耳部。 上述實施形態包含以下之技術思想。 ＜1＞一種溫熱器具，其具備：

surface layer of a living body such as a human body by a warming device having a projection. However, with regard to the warming device of Patent Document 1, there is still room for improvement in achieving such a requirement. The present invention relates to a warming device capable of partially warming a surface layer of a living body such as a human body. Hereinafter, preferred embodiments of the present invention will be described using the drawings. In the drawings, the same components are denoted by the same reference numerals, and the description thereof will be omitted as appropriate. [First Embodiment] As shown in any of Figs. 1 to 4, the heating device 100 of the present embodiment includes a sheet 10 having a convex shape bent toward one surface 10a and an empty side at the other surface 10b side. The protrusion 12 of the cavity 13 and the heat generating material 30 are filled in the cavity 13 of the protrusion 12. By attaching the warming device 100 to a living body such as a human body in a state where the protruding portion 12 is pressed against the skin, the skin of the living body can be pressed against the protruding portion 12 while pressing the skin of the living body with the protruding portion 12. The part is partially warmed up. That is, the surface layer of the living body such as a human body can be sufficiently warmed. Thereby, for example, by applying the pressing of the protruding portion 12 to the fascia of the lower layer of the skin and stimulating by the warming of the heating material 30, the meridian or the meridian can be pressed and warmed by acupuncture. Stimulate. Further, the warming device 100 is hermetically housed in a packaging material (not shown) in a state before use. When the packaging material is unsealed and the warming device 100 is taken out from the packaging material, the oxygen contained in the outside atmosphere is supplied to the heat generating material 30, whereby the heat generating material 30 generates heat. The sheet 10 has a flat sheet-like base portion 11 and a plurality of projection portions 12, and the plurality of projection portions 12 are convexly curved toward the one surface 10a side of the sheet member 10 with reference to the base portion 11. The warming device 100 includes a main body portion 50 that is attached to a portion of the skin of the living body to be warmed. The main body portion 50 includes, for example, a sheet member 10, a heat generating material 30 (FIG. 3) filled in the cavity 13 of the protruding portion 12 of the sheet member 10, and a second sheet member 20 (FIG. 3). The sheet 10 is laminated on the other surface 10b side with respect to the sheet 10, and the water-absorbent sheet 40 (FIG. 3) is laminated between the second sheet 20 and the base 11. Further, the heating device 100 may not include the water-absorbent sheet 40 depending on the composition of the heat-generating material 30 or the like. In the following description, in the main body portion 50, the protruding direction of the protruding portion 12 (the lower side in FIG. 3) is referred to as the front surface side, and the direction opposite to the protruding direction of the protruding portion 12 is ( The upper part in Fig. 3 is referred to as the rear surface side. The planar shape of the main body portion 50 is not particularly limited. For example, as shown in FIG. 2, a rectangular shape (for example, a square shape) in which four corner portions are each formed into a chamfered shape can be used. However, the planar shape of the body portion 50 may be other shapes such as a polygon other than a rectangle, a circle, and an ellipse. The sheet 10 constitutes a front surface side outer surface of the body portion 50. For example, the warming device 100 is used in a state where the sheet 10 (especially, the protruding portion 12) is in direct contact with the skin of the living body. In the case of the present embodiment, the sheet 10 includes one layer of the nonwoven fabric sheet 15 (Fig. 4). Further, the second sheet 20 constitutes the outer surface of the rear surface side of the main body portion 50. The sheet 10 and the second sheet 20 are formed, for example, in the same planar shape, and overlap each other in a state in which the lines are aligned with each other, and the peripheral portions of the mutually adjacent portions are joined to each other. Thereby, the water absorbing sheet 40 is held between the base portion 11 of the sheet 10 and the second sheet 20. Further, the heat generating material 30 is held between the inner circumferential surface of the protruding portion 12 of the sheet 10 and the water-absorbent sheet 40. The heat generating material 30 is composed of, for example, an oxidizable metal, a humectant, and water. The heat generating material 30 generates heat by supplying oxygen to the oxidizable metal in the heat generating material 30. Further, the heat generating material 30 may be one containing iron or carbon. The iron referred to herein may be at least a part of the above oxidizable metal, or may be different from the above oxidizable metal. The iron referred to here is oxidizable iron. Further, the carbon component described herein may be at least a part of the above-mentioned humectant, and the heat generating material 30 may further contain a carbon component in addition to the above humectant. In the main body portion 50, a portion corresponding to the protruding portion 12 of the sheet 10 may be filled with the heat generating material 30, and a portion corresponding to the base portion 11 may be filled between the sheet 10 and the second sheet 20. There is heating material 30. However, in this case, it is also preferable that the thickness of the heat generating material 30 at a portion corresponding to the protruding portion 12 of the sheet 10 is larger than the thickness of the heat generating material 30 at a portion corresponding to the base portion 11. More preferably, the heat generating material 30 is partially filled in a portion corresponding to the protruding portion 12 of the sheet 10, and the heat generating material 30 is not present in at least a portion of the portion corresponding to the base portion 11. In the case of the present embodiment, the heat generating material 30 is filled in the portion corresponding to the protruding portion 12 in the sheet 10, whereas the heat generating material 30 is substantially not present in the portion corresponding to the base portion 11. The heat generating material 30 is preferably filled in the cavity 13 at least at a portion corresponding to the front end portion of the protrusion portion 12. Thereby, the skin of the living body can be warmed by the front end of the protrusion 12. For example, it is preferable that the region corresponding to 50% or more from the lower end side in FIG. 4 in the height direction of the cavity 13 (the region corresponding to the lower half of the range indicated by the height dimension H2 in FIG. 4) is filled with Heating material 30. More specifically, in the case of the present embodiment, the heat generating material 30 is filled, for example, in a region of 70% or more in the height direction of the cavity 13. That is, as shown in FIG. 4, the height dimension of the region in which the heat generating material 30 is filled in the cavity 13 is 0.7 H2 or more with respect to the height dimension H2 of the cavity 13. Thereby, the protrusions 12 can be more sufficiently heated, and the skin of the living body can be sufficiently warmed by the protrusions 12. Further, the heat generating material 30 is preferably filled in a region of, for example, 90% or more in the height direction of the cavity 13. That is, the height dimension of the region in which the heat generating material 30 is filled in the cavity 13 is preferably 0.9 H2 or more. Thus, the filling rate of the heat generating material 30 in the height direction of the cavity 13 is preferably 70% or more, and more preferably 90% or more. In the case of the present embodiment, for example, the rear surface (the upper surface in Fig. 4) of the base portion 11 of the sheet 10 and the rear surface (the upper surface in Fig. 4) of the heat generating material 30 are flush with each other. Here, a method of measuring the filling rate of the heat generating material 30 in the height direction of the cavity 13 will be described. As the measuring device, a laser microscope or a laser displacement meter capable of measuring the height difference is used. As the laser displacement meter, a one-dimensional spot type, a two-dimensional laser displacement meter, and a three-dimensional laser displacement meter can be used. According to the shape and height dimension of the protrusion 12, an appropriate laser displacement meter is selected based on the required measurement distance and the spot distance of the laser light. For example, a sensor head manufactured by KEYENCE can be used; IL-300 (measuring distance 160 mm to 450 mm, spot diameter f 500 μm). For the measurement, the main body portion 50 is taken out from the heating device 100 in a nitrogen atmosphere so that the heat generating material 30 does not generate heat, and the second sheet 20 and the water absorbing sheet 40 are removed from the sheet 10 to form the cavity 13 The surface on the proximal end side of the protruding portion 12 of the heat generating material 30 (the upper surface of the heat generating material 30 in Fig. 4) is exposed. The measurement by the measuring device is performed in such a manner that the sheet 10 is vertically irradiated with laser light. In this measurement, the height difference between the surface on the proximal end side of the projection 12 of the heat generating material 30 (the upper surface of the heat generating material 30 in FIG. 4) and the other surface 10b of the sheet 10 was measured. At this time, the laser light is scanned in the radial direction of the surface (which also coincides with the diameter direction of the protrusion 12) so that the laser light passes through the center of the surface on the base end side of the protrusion 12 of the heat generating material 30. Find the maximum value of the height difference. At this time, the scanning distance is set to be longer than the diameter of the protrusion 12. The height dimension of the heat generating material 30 is a value obtained by subtracting the maximum value of the height difference obtained by the measurement from the height dimension H2 shown in FIG. Here, when the shape of the inner circumferential surface of the projection 12 and the shape of the outer circumferential surface of the projection 12 (the shape of the outer circumferential surface of the cavity 13) are substantially equal, as the height dimension H2, for the sake of convenience, The height dimension H1 shown in Fig. 4 is used. That is, the height dimension of the heat generating material 30 is a value obtained by subtracting the maximum value of the height difference obtained by the measurement from the height dimension H1. Therefore, the height dimension H1 was measured in the following manner. In other words, the front surface of the sheet 10 is disposed so as to be reversed when the measurement of the height difference is performed, and the maximum value of the height difference when the laser light is scanned is obtained by the apex of the protrusion portion 12. At this time, the laser light is scanned in the radial direction of the protrusion 12, and the scanning distance is set to be longer than the diameter of the protrusion 12. On the other hand, when the shape of the inner circumferential surface of the projection 12 is different from the shape of the outer circumferential surface of the projection 12 (the shape of the outer circumferential surface of the cavity 13), for example, the outer peripheral surface of the cavity 13 is a frustum In the case of the shape, the heat generating material 30 entering the cavity 13 is removed in a nitrogen atmosphere. At this time, the bristles or the like are used, and the heat generating material 30 is removed while not changing the shape of the cavity 13. Further, similarly to the measurement of the maximum value of the height difference, the height dimension (height dimension H2) of the cavity 13 is measured by scanning the laser light. The shape of the protrusion 12 is not particularly limited, and is, for example, a shape that tapers toward the distal end side. However, the front end portion of the projection portion 12 preferably has a curved shape. The shape of the protrusion 12 can be, for example, a conical shape such as a conical shape, an elliptical cone shape or a long conical shape, or a truncated cone shape such as a truncated cone shape, an elliptical frustum shape or a long truncated cone shape. In the case of this embodiment, the shape of the protrusion 12 is formed in a conical shape. The height dimension H1 (FIG. 4) of the protrusion 12 is not particularly limited, and is, for example, preferably 2 mm or more and 15 mm or less, more preferably 3 mm or more and 10 mm or less, and still more preferably 5 mm or more and 8 mm or less. . Since the height H1 of the protrusion 12 is 2 mm or more and 15 mm or less, the protrusion 12 can sufficiently and appropriately press the skin of the living body. The diameter of the protrusion 12 is not particularly limited, and is, for example, preferably 2 mm or more and 38 mm or less, and more preferably 5 mm or more and 20 mm or less. Since the diameter of the protruding portion 12 is 2 mm or more and 38 mm or less, the skin of the living body can be sufficiently and appropriately pressed by the protruding portion 12. The inclination angle α ( FIG. 4 ) of the protrusion 12 is not particularly limited, and is preferably, for example, 30 degrees or more, and more preferably 45 degrees or more. Since the inclination angle α of the protruding portion 12 is 30 degrees or more, the skin of the living body can be sufficiently pressed by the protruding portion 12. Further, the inclination angle α of the protruding portion 12 is preferably 80 degrees or less, more preferably 70 degrees or less, and still more preferably 65 degrees or less. Since the inclination angle α of the projection 12 is 80 degrees or less, the projection 12 can be placed in an appropriate range with respect to the skin of the living body. Further, as described above, the front end portion of the protruding portion 12 is preferably in the shape of a curve. Further, the radius of curvature of the front end portion of the protruding portion 12 is preferably 0.5 mm or more and 3.0 mm or less, and more preferably 0.8 mm or more and 1.5 mm or less. Here, for example, if it is a part of the shoulder of the human body, the fascia is located at a depth of about 6 mm from the surface of the skin, preferably in such a manner that the pressing action and the heating action reach the depth, and the shape of the protrusion 12 is set and The heating performance of the heating material 30. In addition, the heat generation performance of the heat generating material 30 is preferably set such that the temperature of the surface of the skin is 37° C. or higher and 44° C. or lower, and more preferably set to 38° C. or higher and 42° C. or lower. . The arrangement of the plurality of protrusions 12 is not particularly limited, and may be, for example, a zigzag lattice shape or a square lattice shape. In the case of the present embodiment, for example, as shown in FIG. 2, the sheet 10 has five projections 12 arranged in a zigzag lattice shape. More specifically, one projection 12 is disposed in the center portion of the sheet 10, and the remaining four projections 12 are disposed around the projection 12. The four projections 12 are disposed at four corners of the sheet 10, respectively. The distance L between the centers of the adjacent protrusions 12 (FIG. 2) is not particularly limited, but is preferably equal to or greater than the height H1 (FIG. 4) of the protrusions 12, and more preferably 1.5 times or more the height H1. Thereby, the skin of the living body can be sufficiently pressed by the respective protrusions 12. Here, when the projections 12 are pressed in the vertical direction of the sheet 10 in a state where the sheet 10 of the heat generating material 30 is not filled in the projections 12, it is preferable for each of the projections 12 In other words, under the force of 1 N, the protrusion 12 is substantially not plastically deformed and deformed by the protrusion 12 in a range in which the elastic deformation occurs, and the protrusion 12 is plastically deformed under a force of 25 N, and the protrusion 12 is set. The load resistance is further preferably a deformation of the protrusion 12 in a range in which the protrusion 12 is substantially not plastically deformed and elastically deformed under a force of 5 N for each of the protrusions 12, at 18 N The force of the protrusion 12 is set to be plastically deformed, and the load resistance of the protrusion 12 is set. By doing so, the skin of the living body can be sufficiently pressed by the protruding portion 12, and the protruding portion 12 can be placed in an appropriate range with respect to the skin of the living body. Here, the vertical direction of the sheet 10 is the normal direction of the sheet 10 (the direction orthogonal to the one surface 10a of the sheet 10). Further, when the projections 12 of the main body portion 50 in which the heat generating material 30 is filled in the projections 12 are pressed in the vertical direction of the sheet 10, it is preferable that for each of the projections 12, The load of the portion corresponding to the protrusion 12 in the main body portion 50 is set so that the protrusion portion 12 is substantially not plastically deformed and the protrusion portion 12 is deformed in the range of elastic deformation, and further preferably The load resistance of the portion of the main body portion 50 corresponding to the projection portion 12 is set so that the projection portion 12 is substantially not plastically deformed and the projection portion 12 is deformed in a range in which the elastic deformation is performed under a force of 5 N. By doing so, the skin of the living body can be sufficiently pressed by the protruding portion 12, and the protruding portion 12 can be placed in an appropriate range with respect to the skin of the living body. At least one of the sheet 10 and the second sheet 20 which constitute the outer surface before and after the main body portion 50 has gas permeability. Thereby, oxygen can be supplied to the heat generating material 30 by at least one of the sheet 10 or the second sheet 20, and the heat generating material 30 can be heated. In the case of the present embodiment, for example, the sheet 10 has gas permeability, and the air permeability of the sheet 10 is higher than that of the second sheet 20. More specifically, the sheet 10 also has gas permeability in the protruding portion 12, and oxygen can be supplied to the heat generating material 30 via the protruding portion 12, and water vapor can be released via the protruding portion 12. More specifically, in the case of the present embodiment, the second sheet 20 is, for example, a non-gas permeable sheet that does not substantially pass air. The water-absorbent sheet 40 is laminated on the other surface 10b side of the sheet 10 with respect to the base portion 11. In other words, the heating device 100 includes the water-absorbent sheet 40 (FIG. 3) which is laminated on the other surface 10b side with respect to the base portion 11 of the sheet 10. Since the warming device 100 is provided with the water-absorbent sheet 40, the remaining water in the heat-generating material 30 can be absorbed by the water-absorbent sheet 40. Thereby, when the warming device 100 is taken out from the packaging material, the heat generating material 30 can be rapidly heated. As the water-absorbent sheet 40, for example, a sheet containing a water-absorbent polymer, a woven non-woven fabric, a cellulose non-woven fabric, or paper can be used. Among them, the water-absorbent sheet 40 is preferably composed of a water-absorptive polymer, and the water-absorbent sheet 40 may be obtained by forming a water-absorbent polymer into a sheet shape. The water-absorbent sheet 40 preferably covers at least the rear surface side of each of the protrusions 12. In this case, the water-absorbent sheet 40 covers the surface side after the filling region of the heat-generating material 30 filled in each of the protrusions 12. Thereby, the moisture in the heat generating material 30 filled in each of the protrusions 12 can be preferably absorbed by the water-absorbent sheet 40. Further, in the present embodiment, the warming device 100 may have a water-absorbent polymer which is disposed discontinuously (disposed in a non-sheet shape) instead of the water-absorbent sheet 40. Further, in the case of the present embodiment, the heat generating material 30 preferably does not substantially contain the water-absorbent polymer, and thus the content ratio of the oxidizable metal in the heat-generating material 30 can be sufficiently ensured, so that it is sufficient The heat generation time of the heating material 30 and the duration of the heat generation are ensured. The heating device 100 includes a bonding portion 60 for bonding the heating device 100 to the living body in a state where the protruding portion 12 is pressed against the skin. The bonding unit 60 is configured to include, for example, a pair of strip-shaped strip portions 61 which are formed in a strip shape in a single direction (the horizontal direction in FIG. 2). As described above, in the case of the present embodiment, the planar shape of the main body portion 50 is a rectangle. For example, the base end portion 66 which is one end portion of each of the bonding belt portions 61 in the longitudinal direction is fixed along one of the facing edges of the main body portion 50. The bonding tape portion 61 includes a sheet-like bonding portion constituting the sheet 63 and an adhesive layer 64 formed on one surface of the portion on the front end side of the bonding portion constituting the sheet 63. The adhesive layer 64 is formed on the skin side surface when the heating device 100 is bonded to the living body in the bonding portion constituting sheet 63. In this manner, the bonding portion 60 includes an adhesive sheet portion that is adhered and fixed to the skin (for example, a portion where the adhesive portion 64 is formed in the bonding portion constituting sheet 63).

By setting the content to 0.5% by mass or more, the oxidation reaction of the heat generating material 30 can be sufficiently performed, and the ratio of the moisture of the heat generating material 30 can be suppressed in order to secure the electrolyte required for the heat generating function. The ground ensures that the heating temperature rises. By setting the content to 24% by mass or less, the gas permeability of the heat generating material 30 can be improved, and the moisture ratio in the heat generating material 30 can be maintained to some extent in order to secure the electrolyte required for the heat generating function. The size is such that sufficient water can be supplied to the oxidizable metal or the like, and the heat generation performance is excellent, and the electrolyte can be uniformly mixed in the heat generating material 30, which is preferable.

The basis weight of the nonwoven fabric sheet 15 is 15 g/m ² or more and 500 g/m ² or less, and particularly preferably 30 g/m ² or more and 350 g/m ² or less. Since the basis weight of the nonwoven fabric sheet 15 is 15 g/m ² or more, sufficient strength of the sheet 10 can be ensured, and the temperature of the heat generating material 30 can be moderately moderated and then transmitted to the skin. Since the basis weight of the nonwoven fabric sheet 15 is 500 g/m ² or less, the temperature of the heat generating material 30 can be efficiently transmitted to the skin via the sheet 10 .

By setting the moisture permeability of the second sheet 20 to such a range, the second sheet 20 can be used to restrict the generation direction of the water vapor accompanying the heat generation of the heat generating material 30. For example, oxygen is supplied to the heat generating material 30 from the sheet 10 side, and generation of water vapor from the second sheet 20 can be suppressed, and water vapor can be mainly generated from the sheet 10 side. The basis weight of the second sheet 20 is preferably 10 g/m ² or more and 200 g/m ² or less, and 20 g/m ² or more and 100 g/m ² or less.

The material of the bonding portion constituting the sheet 63 is not particularly limited, and for example, it can be a non-woven fabric having stretchability. Examples of the material of the nonwoven fabric include synthetic fibers, natural fibers, and composite fibers of the above. However, the bonding portion constituting sheet 63 is not limited to a non-woven fabric, and may be, for example, a woven fabric in which rubber fibers are embedded. The material of the adhesive layer 64 is not particularly limited, and for example, an adhesive material such as a rubber type, an acrylic resin type, an anthrone type, a latex type, a hot melt type, or a hydrogel type can be used. Next, a method of manufacturing the warming device of the present embodiment will be described. The method for manufacturing a warming device according to the present embodiment includes the steps of forming the protrusions 12 on the sheet 10 by pressing, and filling the heat generating material 30 in the cavity 13 of the protrusions 12. In order to form the projections 12 on the sheet 10, first, the nonwoven fabric sheet 18 which is a raw material of the nonwoven fabric sheet 15 is prepared. Here, the nonwoven fabric sheet 18 is configured to include, for example, a first fiber including a first resin material and a second fiber including a second resin material (a case where a first fiber and a second fiber are mixed). However, the fiber constituting the nonwoven fabric sheet 18 may have a core sheath structure including a core including a first resin material and a sheath including a second resin material. Next, the sheet 10 on which the projections 12 are formed is formed by hot pressing the nonwoven fabric sheet 18. Here, the temperature of the hot pressing is set to a temperature intermediate between the melting point of the first resin material and the melting point of the second resin material. That is, the temperature of the hot pressing is set to a temperature not higher than the melting point of the first resin material and higher than the melting point of the second resin material. Thereby, the second resin material can be melted, and the first resin material is not melted. Therefore, the second resin material is melted to include the fibers of the first resin material (the fibers may be cores of the core-sheath structure). Partly) glued to each other. That is, the molten second resin material constitutes a bonding portion that bonds the fibers including the first resin material to each other. As a result, the gas permeability of the sheet 10 can be ensured, and the rigidity of the sheet 10 can be sufficiently ensured. In other words, the gas permeability and rigidity of the base portion 11 can be sufficiently ensured, and the protrusion portion 12 can have sufficient air permeability from the base end of the projection portion 12 to ensure the gas permeability while ensuring the entire body. Here, the temperature of the hot pressing is preferably set to be as low as possible within a range in which the second resin material can be sufficiently melted (for example, the melting point of the second resin material + 30 ° C or lower, preferably the second resin material). The melting point + temperature below 20 ° C). As a result, the nonwoven fabric sheet 15 after the hot pressing can have a texture of a non-woven fabric, and the skin feel of the main body portion 50 can be improved. Here, for example, as shown in FIG. 5( a ), the first mold 70 and the second mold 80 which are disposed opposite to each other can be used to form the protrusions 12 on the sheet 10 . The first mold 70 includes a flat surface 71 that faces the second mold 80, and a plurality of protrusions 72 that protrude from the flat surface 71 toward the second mold 80 side. The second mold 80 includes a flat surface 81 that faces the first mold 70 and a plurality of concave portions 82 that are formed in a portion of the flat surface 81 that faces each of the projections 72. As shown in FIG. 5(b), the first mold 70 and the second mold 80 are brought into close proximity to each other, and the sheet 10 is pressed in the thickness direction, and the sheet 10 is formed by the first mold 70 and the second mold 80. Heating is performed to form a plurality of protrusions 12 on the sheet 10. In the sheet 10, the portion corresponding to the flat surfaces 71 and 81 of the first metal mold 70 and the second mold 80 serves as the base portion 11, and the portions corresponding to the projection portions 72 and the concave portions 82 of the first metal mold 70 and the second mold 80 become Projection portion 12. After the protrusions 12 are formed on the sheet 10, the heat generating material 30 is filled in the protrusions 12. To this end, a raw material composition (slurry) containing a heat-generating material 30 of an oxidizable metal, a humectant, and water is prepared, and the raw material composition is introduced into each of the protrusions 12. Thereby, the heat generating material 30 can be filled in the shape of the inner peripheral surface of the protrusion part 12. Thereby, the shape of the heat generating material 30 can be set to the shape of a taper shape or a frustum shape similar to the shape of the protrusion part 12, for example. After the heat generating material 30 is filled in each of the protrusions 12 of the sheet 10, the water-absorbent sheet 40 is laminated on the base portion 11 of the sheet 10. Further, the second sheet 20 is laminated on the water-absorbent sheet 40, and the peripheral edge portion of the second sheet 20 and the peripheral edge portion of the sheet 10 are joined to each other. The joining of the second sheet 20 and the sheet 10 may be carried out using an adhesive or by heat sealing. In this way, the body portion 50 can be fabricated. Next, the base end portions 66 of the pair of bonding belt portions 61 are joined to the main body portion 50, respectively. The bonding of the bonding tape portion 61 to the main body portion 50 may be performed using an adhesive or by heat sealing. In this way, the heating device 100 is manufactured. According to the first embodiment as described above, the heating device 100 includes the sheet member 10 having the protrusion portion 12 which is convexly curved toward the one surface 10a side and which is the cavity 13 on the other surface 10b side, and the heat generating material 30 which is The cavity 13 is filled in the protrusion 12. Therefore, by attaching the warming device 100 to a living body such as a human body in a state in which the protruding portion 12 is pressed against the skin, the skin of the living body can be pressed against the skin of the living body by the protruding portion 12 while pressing the living body. The corresponding part of 12 is partially warmed up.

[Second Embodiment] Next, a second embodiment will be described with reference to Figs. 8 to 9(b). The warming device 100 of the present embodiment differs from the warming device 100 of the above-described first embodiment in the configuration of the sheet member 10, and is otherwise identical to the warming device 100 of the first embodiment. In the first embodiment described above, an example in which the sheet 10 includes one sheet of the nonwoven fabric sheet 15 has been described. On the other hand, in the present embodiment, the sheet 10 is composed of a non-woven sheet 15 (first nonwoven sheet) constituting one of the outermost layers of the sheet 10; and a non-woven sheet 17 ( The second nonwoven fabric sheet constitutes the other outermost layer of the sheet material 10; and the air permeable sheet member 16 is configured to be an intermediate layer between the first nonwoven fabric sheet and the second nonwoven fabric sheet. More specifically, in the case of the present embodiment, the sheet 10 has a three-layer structure of the nonwoven fabric sheet 15, the air permeable sheet material 16, and the nonwoven fabric sheet 17, for example, as shown in FIG. However, the present invention is not limited to this example, and the sheet 10 may be composed of three layers of the nonwoven fabric sheet 15, the gas permeable sheet 16, and the nonwoven fabric sheet 17. As an example, the sheet material 10 may include two layers of the gas permeable sheet 16 between the nonwoven fabric sheet 15 and the nonwoven fabric sheet 17, and further include a third nonwoven fabric sheet between the two layers of the air permeable sheets 16 and It is a layer structure of a total of five layers. As described in the first embodiment, the nonwoven fabric sheet 15 includes a fiber including a first resin material and a bonding portion including a second resin material and bonding the fibers to each other. Further, the nonwoven fabric sheet 17 is also composed of a fiber including a first resin material and a bonding portion including a second resin material and bonding the fibers to each other, similarly to the nonwoven fabric sheet 15. In other words, each of the first nonwoven fabric sheet and the second nonwoven fabric sheet includes a fiber including a first resin material and a bonding portion including a second resin material and bonding the fibers to each other. However, the first resin material constituting the nonwoven fabric sheet 15 and the first resin material constituting the nonwoven fabric sheet 17 may be the same material or different materials. Further, the second resin material constituting the nonwoven fabric sheet 15 and the second resin material constituting the nonwoven fabric sheet 17 may be the same material or different materials. In the case of the present embodiment, for example, the nonwoven fabric sheet 15 and the nonwoven fabric sheet 17 are made of the same material, and the first resin material constituting the nonwoven fabric sheet 15 and the first resin material constituting the nonwoven fabric sheet 17 are mutually The same material and the second resin material constituting the nonwoven fabric sheet 15 and the second resin material constituting the nonwoven fabric sheet 17 are the same material. Moreover, the basis weight of the nonwoven fabric sheet 17 can be appropriately set similarly to the basis weight of the nonwoven fabric sheet 15. Further, in the case of the present embodiment, the fiber constituting the nonwoven fabric sheet 15 may have a core-sheath structure including a core including a first resin material and a sheath including a second resin material. Further, the fiber constituting the nonwoven fabric sheet 17 may be similarly formed into a core sheath structure including a core including a first resin material and a sheath including a second resin material. The gas permeable sheet 16 is composed of a third resin material having a higher melting point than the second resin material. The gas permeability of the gas permeable sheet 16 is not particularly limited. For example, the moisture permeability of the gas permeable sheet 16 is preferably 100 g/(m ² ∙ 24 h) or more and 13,000 g/(m ² ∙ 24 h) or less. It is 200 g/(m ² ∙24 h) or more and 8000 g/(m ² ∙24 h) or less. By setting the moisture permeability of the gas permeable sheet 16 to such a range, when the warming device 100 is taken out from the packaging material, oxygen can be quickly supplied to the heat generating material 30 through the sheet 10, and the heat generating material 30 can be supplied from the heat generating material 30. Heat and water vapor are rapidly generated, and the duration of heat generation is sufficiently long. The measurement of the moisture permeability of the gas permeable sheet 16 can be carried out, for example, by the JIS (Z0208) CaCl ₂ method, and the measurement conditions can be 40 ° C and 90% RH. The breathable sheet 16 may be breathable throughout its entire surface or may be partially breathable. The basis weight of the gas permeable sheet 16 is preferably 10 g/m ² or more and 200 g/m ² or less, and particularly preferably 20 g/m ² or more and 100 g/m ² or less. By setting the basis weight of the gas permeable sheet 16 to such a range, when the warming device 100 is taken out from the packaging material, heat and water vapor can be quickly generated, and the duration of heat generation can be sufficiently long. Examples of the gas permeable sheet 16 include a sheet or the like which comprises a polyolefin or a polyester such as polyethylene or polypropylene, a polyamide, a polyurethane, a polystyrene, a polyethylene-vinyl acetate copolymer. The sheet of the resin is mechanically formed with a vent hole; the interface between the resin and the inorganic filler is peeled off by the extension to provide a fine vent hole; or the interface is peeled off by the crystal structure thereof. A fine venting hole; and a continuous blistering by foam forming to connect the fine vent holes. Further, examples of the gas permeable sheet 16 include non-woven fabrics, woven fabrics, synthetic papers, and papers formed of synthetic pulp such as polyolefin, semi-synthetic fibers such as wood pulp, enamel, and acetate fibers, vinylon fibers, and polyester fibers. Wait. The breathable sheet 16 can also be used by overlapping a plurality of sheets. More specifically, as the gas permeable sheet 16, the interface between the polypropylene and the calcium carbonate is peeled off by stretching, whereby a fine vent hole can be preferably used in the mixed sheet. In the present embodiment, the gas permeable sheet 16 is formed by stretching a mixed sheet of polypropylene and calcium carbonate, and will be described below. Next, a method of manufacturing the warming device of the present embodiment will be described. The method for manufacturing a warming device according to the present embodiment further includes the steps of forming the protruding portion 12 on the sheet 10 by pressing, and filling the heat generating material 30 in the cavity 13 of the protruding portion 12. In order to form the protrusions 12 on the sheet 10, first, the non-woven fabric sheet 18 which is a raw material of the nonwoven fabric sheet 15, the air permeable sheet material 16, and the non-woven fabric sheet 19 which is a raw material of the nonwoven fabric sheet 17 are prepared in accordance with the nonwoven fabric sheet. 18. The three sheets are laminated in such a manner that the breathable sheet 16 and the non-woven sheet 19 are stacked in this order. As described above, the nonwoven fabric sheet 18 includes, for example, a first fiber including a first resin material and a second fiber including a second resin material. However, the fiber constituting the nonwoven fabric sheet 18 may have a core sheath structure including a core including a first resin material and a sheath including a second resin material. The nonwoven fabric sheet 19 is also the same as the nonwoven fabric sheet 18, for example. Then, by laminating the laminated bodies of the three sheets (the nonwoven fabric sheet 18, the gas permeable sheet member 16, and the nonwoven fabric sheet 19), the sheet member 10 having the projections 12 is formed (see FIG. 9 (see FIG. 9). a), Figure 9(b)). In the present embodiment, the temperature of the hot pressing is also set to a temperature intermediate the melting point of the first resin material and the melting point of the second resin material. That is, the temperature of the hot pressing is set to a temperature not higher than the melting point of the first resin material and higher than the melting point of the second resin material. Thereby, the second resin material can be melted, and the first resin material is not melted. Therefore, the second resin material is melted to include the fibers of the first resin material (the fiber may be the core of the core sheath structure). Part of it) glued to each other. That is, the molten second resin material constitutes a bonding portion that bonds the fibers including the first resin material to each other. Thereby, the air permeability of the nonwoven fabric sheet 15 and the nonwoven fabric sheet 17 can be ensured, and the rigidity of the nonwoven fabric sheet 15 and the nonwoven fabric sheet 17 can be sufficiently ensured, so that the air permeability and rigidity of the sheet material 10 can be sufficiently ensured. In other words, the gas permeability and rigidity of the base portion 11 can be sufficiently ensured, and the protrusion portion 12 can have sufficient air permeability from the base end of the projection portion 12 to ensure the gas permeability while ensuring the entire body. In the case of the present embodiment, the temperature of the hot pressing is preferably set to be as low as possible within a range in which the second resin material can be sufficiently melted (for example, the melting point of the second resin material + 30 ° C or lower). Preferably, the melting point of the second resin material is +10 ° C or lower). Thus, the nonwoven fabric sheet 15 and the nonwoven fabric sheet 17 after the hot pressing can have a texture of a non-woven fabric. In particular, the non-woven fabric sheet 17 located on the outer surface side of the main body portion 50 has a texture of non-woven fabric, and the skin feel of the main body portion 50 becomes good. In the case of the present embodiment, the temperature of the hot pressing is preferably set to a temperature lower than the melting point of the third resin material contained in the gas permeable sheet 16 and lower than the extension temperature of the gas permeable sheet 16. Thereby, the vent hole of the gas permeable sheet 16 can be maintained after the hot pressing, thereby ensuring the gas permeability of the gas permeable sheet 16. As described above, in the method of manufacturing the warming device of the present embodiment, the sheet includes the nonwoven fabric sheet 18 (the first nonwoven fabric sheet), which constitutes one of the outermost layers of the sheet; the nonwoven fabric sheet a material 19 (second nonwoven sheet) constituting the other outermost layer of the sheet; and a gas permeable sheet 16 constituting an intermediate layer between the first nonwoven fabric sheet and the second nonwoven fabric sheet; Each of the non-woven fabric sheet and the second non-woven fabric sheet includes a fiber including a first resin material and a second resin material having a lower melting point than the first resin material, and the gas permeable sheet 16 The third resin material having a higher melting point than the second resin material is contained. Further, in the step of forming the protrusion 12 by the sheeting, the sheet is hot-pressed at a temperature intermediate between the melting point of the second resin material and the melting point of the third resin material. In the present embodiment, the three-layer sheet (non-woven sheet) is placed in a state in which the nonwoven fabric sheet 18 and the nonwoven fabric sheet 19 are superposed on each of both surfaces of the gas permeable sheet 16 including the third resin material. The material 18, the gas permeable sheet 16 and the nonwoven fabric sheet 19) are hot pressed, whereby the projections 12 are formed. Thereby, both sides of the gas permeable sheet 16 can be protected by the nonwoven fabric sheets 18, 19 at the time of hot pressing. Therefore, even when the gas permeable sheet 16 provided in the heat-pressing sheet 10 contains, for example, a third resin material having high crystallinity such as polypropylene, the rupture of the gas permeable sheet 16 can be suppressed. The protrusion 12 is formed on the sheet 10. Thereby, the sheet 10 can be made to have uniform gas permeability over the entire surface. Moreover, the sheet 10 after the hot pressing has a laminated structure in which the nonwoven fabric sheets 15 and 17 are disposed on both surfaces of the gas permeable sheet 16 . Therefore, the rigidity of the sheet 10 can be more easily ensured, and in particular, the protrusion 12 can also securely ensure rigidity. Further, in the sheet 10 after the hot pressing, the second resin material of the nonwoven fabric sheet 15 and the second resin material of the nonwoven fabric sheet 17 may be adhered to the breathable sheet 16 or may not be bonded to the breathable sheet 16. In the case of the present embodiment, the second resin material of the nonwoven fabric sheet 15 and the second resin material of the nonwoven fabric sheet 17 are not bonded to the gas permeable sheet 16, whereby the gas permeable property of the gas permeable sheet 16 can be favorably maintained. The manufacturing steps after the protrusions 12 are formed on the sheet 10 are the same as those in the first embodiment, and thus the description thereof is omitted. In this way, the heating device 100 of the present embodiment is manufactured. According to the second embodiment, the sheet 10 is composed of a non-woven sheet 15 (first nonwoven sheet) constituting one of the outermost layers of the sheet 10, and a non-woven sheet 17 (second non-woven sheet) a material constituting the other outermost layer of the sheet 10; and a gas permeable sheet 16 constituting an intermediate layer between the first nonwoven fabric sheet and the second nonwoven fabric sheet. Thereby, the rigidity of the sheet 10 can be more easily ensured, and in particular, the protrusions 12 can ensure good rigidity, and the skin of the living body can be more sufficiently pressed by the protrusions 12. Further, the gas permeable sheet 16 is composed of a third resin material, and the melting point of the third resin material is higher than the melting point of the second resin material constituting the nonwoven fabric sheets 15 and 17, so that the gas permeable sheet 16 can be easily maintained. A warming device 100 of breathable construction. In the second embodiment, an example in which a mixed sheet of polypropylene and calcium carbonate is used as the gas permeable sheet 16 is mainly described. However, the present invention is not limited to this example. For example, the gas permeable sheet 16 may be produced by forming a plurality of fine pores from a resin sheet containing a third resin material. That is, the gas permeable sheet 16 is, for example, a resin sheet including a third resin material, and has a plurality of pores penetrating the front surface of the gas permeable sheet 16. Further, it is also preferable that the non-woven fabric sheet 18 and the non-woven fabric sheet 19 are bonded to each other on both surfaces of the gas permeable sheet 16 at the time of the hot pressing, and the nonwoven fabric is bonded to the breathable sheet 16 in advance, and the breathable sheet 16 is reinforced. . [Third Embodiment] Next, a third embodiment will be described with reference to Fig. 10 . The warming device 100 of the present embodiment is different from the warming device 100 of the first embodiment or the second embodiment in the following description, and is otherwise configured to be in the first embodiment or the second embodiment. The form of the warming device 100 is the same. In the case of the present embodiment, the heating device 100 is configured to include the bonding portion 60 and the main body portion 50 described below. In the case of the present embodiment, the bonding portion 60 and the main body portion 50 are initially separated as shown in Fig. 10 . For example, the user can use the warming device 100 by attaching the main body portion 50 to the bonding portion 60 at the time of use or the like. The bonding unit 60 includes a pair of bonding tape portions 61 and a base sheet 111 to which the bonding tape portions 61 are attached. The planar shape of the base sheet 111 is, for example, the same as the planar shape of the body portion 50. Each of the pair of bonding belt portions 61 is attached to both end portions of the base sheet 111, whereby the pair of bonding belt portions 61 are coupled to each other via the base sheet 111. The material of the base sheet 111 is not particularly limited. The base sheet 111 may be, for example, a non-woven sheet or a resin sheet. Regardless of whether or not the base sheet 111 has gas permeability. The main body portion 50 includes, for example, an adhesive layer 112 formed on a surface of the second sheet 20 that is the outer surface side of the main body portion 50. Further, in the state before use of the heating device 100, the same release paper as the release paper 65 is attached to the adhesive layer 112, and the adhesive layer 112 is covered with the release paper. When the warming device 100 is used, the release paper is peeled off from the adhesive layer 112, and the adhesive layer 112 is attached to the base sheet 111, whereby the main body portion 50 is attached to the bonding portion 60. Thereafter, the warming device 100 can be attached to the living body as described in the first embodiment, and the protruding portion 12 can be pressed against the skin of the living body. In the case of the present embodiment, the main body portion 50 has a plurality of protrusions 12 as in the first embodiment and the second embodiment. That is, the main body portion 50 is a projection unit including a plurality of protrusions 12 and heat generating materials 30 filled in the cavities 13 of the protrusions 12, respectively. Further, it is also preferable to repeatedly bond and peel the adhesive layer 112 to the base sheet 111. As a result, the main body portion 50 can be discarded. On the other hand, the plurality of main body portions 50 can be sequentially attached and detached to the one bonding portion 60, and the bonding portion 60 can be used repeatedly. Furthermore, the body portion 50 can be detachably attached to the bonding portion 60 by the surface fastener. [Fourth embodiment] Next, a fourth embodiment will be described with reference to Figs. 11(a) to 12(b). The warming device 100 of the present embodiment is different from the warming device 100 of the above-described third embodiment in the following description, and is otherwise identical to the warming device 100 of the third embodiment. In the case of the present embodiment, the heating device 100 may include the bonding tool 114 (bonding portion) described below instead of the bonding portion 60 (FIG. 11(b)). As shown in FIG. 11(b), the bonding tool 114 is integrally formed of, for example, an elastically deformable resin material, but is not limited to the integrally formed structure. The bonding tool 114 includes a pair of opposing portions 115 that are disposed to face each other, and a connecting portion 116 that connects the opposing portions 115 to each other. Each of the pair of opposing portions 115 is formed in a plate shape. Further, for example, the connecting portion 116 is also formed in a plate shape. Therefore, the bonding tool 114 as a whole has a shape in which a plate which is elongated in one direction is bent in a U shape. The fitting 114 is elastically deformable in a direction in which the opposing faces of the pair of opposing portions 115 are enlarged. In a state where the opposing interval between the pair of opposing portions 115 is enlarged, the bonding tool 114 is elastically restored (elastically restored) to the initial form, whereby the bonding tool 114 has a direction toward the pair of opposing portions 115. The pressure applied in the direction in which the interval is narrowed. A curved portion 117 is formed, for example, at a front end of each of the pair of opposing portions 115. The curved portion 117 at the front end of the pair of facing portions 115 is curved away from the other opposing portion 115. Similarly, the curved portion 117 of the other opposing portion 115 is curved away from the pair of facing portions 115. However, the fitting 114 may not have the curved portion 117. For example, in the pair of opposing portions 115, a plurality of ribs 118 are formed on the surfaces facing each other. The plurality of ribs 118 extend, for example, parallel to each other. However, the fitting 114 may not have the rib 118. In the case of this embodiment, as shown in FIG. 11(a), the main body portion 50 is formed in a long strip in one direction. For example, the plurality of protrusions 12 are arranged in a line. In the case of the present embodiment, the main body portion 50 also includes the same adhesive layer 112 as in the third embodiment (see Fig. 12(b)). Further, in a state before use of the heating device 100, a release paper is attached to the adhesive layer 112. When the warming device 100 is used, the release paper is peeled off from the adhesive layer 112, and the adhesive layer 112 is attached to the inner surface of the bonding tool 114, whereby the main body portion 50 is attached to the bonding tool 114. In this state, the protruding portion 12 is preferably disposed at a position corresponding to the opposing portion 115, and is not disposed at a position corresponding to the connecting portion 116 (see FIG. 12(b)). In a state in which the main body portion 50 is attached to the bonding tool 114, the opposing distance between the pair of opposing portions 115 is enlarged, and in this state, the palm 113 or the like is inserted into the opposite direction of the pair of opposing portions 115. At the interval, the force for expanding the opposing interval between the pair of opposing portions 115 is released. Thereby, the bonding tool 114 is elastically restored, so that, for example, as shown in FIGS. 12(a) and 12(b), the protruding portion 12 can be crimped to the skin of the portion between the thumb and the index finger in the palm 113, and The acupuncture points and the like located in the portion are pressed by the projections 12. As described above, in the case of the present embodiment, the bonding portion is a bonding tool 114 in which the spacer portion 12 is held by the elastic restoring force by a part of the living body (the palm 113 or the like), whereby the protruding portion 12 is caused. Crimped to the skin. Further, the bonding tool 114 may be provided separately from the warming device 100 and combined with the warming device 100 for the user. In this case, for example, the body portion 50 itself becomes the warming device 100. That is, the bonding tool 114 of the present embodiment is configured to bond the heating device 100 having the protruding portion 12 to the bonding tool 114 of the living body, and to sandwich a part of the living body by the elastic restoring force by the intervening projection portion 12. The protrusion 12 is crimped to the skin. According to the bonding tool 114 of the present embodiment, the heating device 100 having the protruding portion 12 can be attached to the living body, and the protruding portion 12 can be crimped to the living body by the elastic restoring force of the bonding tool 114. skin. Thereby, the protruding portion 12 can be continuously pressed against the skin by the simple fitting member 114. Further, as described above, the bonding tool includes a pair of opposing portions 115 that are disposed to face each other, and a connecting portion 116 that connects the opposing portions 115 to each other; The direction of the opposing portion of the portion 115 is elastically deformed. Here, since the bonding tool 114 includes a plurality of ribs 118, the main body portion 50 can be more stably attached to the bonding tool 114, and the positional displacement of the main body portion 50 with respect to the bonding tool 114 can be suppressed. Further, since the bonding tool 114 includes the curved portion 117, the finger can be caught on the curved portion 117 when the opposing distance between the pair of opposing portions 115 is to be expanded in order to remove the bonding tool 114 from the palm 113 or the like. It is easy to expand the opposing interval of the pair of opposing portions 115. Furthermore, in the present embodiment, the example in which the main body portion 50 is attached to the bonding tool 114 by the adhesive layer 112 is described, and the main body portion 50 may be sandwiched only by the elastic restoring force of the bonding tool 114.
