The skin contact sheet 7 is coated with a temperature-sensitive composition (not shown) on the entire surface thereof, and the entire surface of the skin contact sheet 7 constitutes a temperature-sensing layer 17. In addition, in the temperature-sensitive sheet 1, a temperature-sensing layer overlap region (not shown) that overlaps the temperature-sensing layer 17 in the thickness direction T is formed in the entire planar direction (length direction L and width direction W). The skin contact sheet 7 includes a skin contact surface 31 and a skin non-contact surface 33.

於溫感薄片1，肌膚抵接薄片7、中間層9、具有液體非穿透性的衣服抵接薄片11、剝離薄片15之各者，係平面方向(長度方向L及寬度方向W)的外緣的形狀相同，且肌膚抵接薄片7、中間層9、具有液體非穿透性的衣服抵接薄片11、剝離薄片15係以該等的外緣在厚度方向T一致的方式受到堆疊。 Each of the temperature-sensitive sheet 1, the skin abutment sheet 7, the intermediate layer 9, the liquid-impermeable clothes abutment sheet 11, and the release sheet 15 are in the plane direction (length direction L and width direction W). The edges have the same shape, and the skin contact sheet 7, the intermediate layer 9, the liquid non-penetrating clothes contact sheet 11, and the release sheet 15 are stacked in such a manner that the outer edges thereof are uniform in the thickness direction T.

溫感薄片1，係在長度方向L的中心，具備平行於寬度方向W而延伸的折軸F。又，於單個包裝體3，溫感薄片1係以折軸F作為基準，以肌膚抵接薄片7的肌膚抵接面31為內側作摺疊，並被包裝薄片5所包裝。 The temperature-sensitive sheet 1 is provided at the center of the longitudinal direction L and includes a folding axis F extending parallel to the width direction W. Furthermore, in the single package 3, the temperature-sensitive sheet 1 is folded using the folding axis F as a reference, and the skin-contacting surface 31 of the skin-contacting sheet 7 is folded inside, and is packaged by the packaging sheet 5.

固定部13，係由複數個固定部部分14構成。複數個固定部部分14之各者，係分別朝向寬度方向W延伸，並到達溫感薄片1的寬度方向W的兩端部。複數個固 定部部分14，係在長度方向L隔著預定的間隔作配置。 The fixing portion 13 is composed of a plurality of fixing portion portions 14. Each of the plurality of fixing portion portions 14 extends toward the width direction W and reaches both ends of the temperature-sensitive sheet 1 in the width direction W. Multiple solid The fixed portion 14 is arranged at a predetermined interval in the longitudinal direction L.

剝離薄片15，係外緣形狀與衣服抵接薄片11相同，並以覆蓋固定部13(複數個固定部部分14)之整體的方式作配置。 The release sheet 15 has the same outer edge shape as the clothes contact sheet 11 and is disposed so as to cover the entire fixed portion 13 (a plurality of fixed portion portions 14).

如第1圖所示，溫感薄片1係在被對折的狀態，受到包裝薄片5所包裝，而形成單個包裝體3。具體而言，單個包裝體3，係藉由將以折軸F作為基準，以肌膚抵接薄片7的肌膚抵接面31為內側作對折的溫感薄片1，以2枚包裝薄片5夾住，並在2枚包裝薄片5的周緣部設置密封部101而形成。 As shown in FIG. 1, the temperature-sensitive sheet 1 is folded in half, and is packaged by the packaging sheet 5 to form a single packaging body 3. Specifically, the single package 3 is a warm sheet 1 that is folded in half with the skin contact surface 31 of the skin contact sheet 7 with the folding axis F as a reference, and is sandwiched by two packaging sheets 5 A sealing portion 101 is provided on the peripheral edge portion of the two packaging sheets 5.

佩帶者係從單個包裝體3的缺口部103，將單個包裝體3開封，從單個包裝體3取出溫感薄片1，並將剝離薄片15從溫感薄片1剝離。接著，如第6圖所示，佩帶者係將溫感薄片1的固定部13固定於衣服21，具體而言係固定於內褲的內面，並在溫感薄片1的肌膚抵接面31抵接於佩帶者的肌膚的狀態下使用溫感薄片1。 The wearer unsealed the single package 3 from the cutout portion 103 of the single package 3, took out the temperature-sensitive sheet 1 from the single package 3, and peeled the release sheet 15 from the temperature-sensitive sheet 1. Next, as shown in FIG. 6, the wearer fixes the fixing portion 13 of the temperature-sensitive sheet 1 to the clothing 21, specifically, the inner surface of the underwear, and abuts on the skin-contacting surface 31 of the temperature-sensitive sheet 1. The heat-sensitive sheet 1 is used while being in contact with the wearer's skin.

溫感薄片1係如第3圖及第4圖所示，具有位在自溫感薄片1的外周緣23起的預定的距離範圍內的區域的周緣部25。溫感薄片1，係於周緣部25不具有壓花部。藉此，佩帶者在佩帶溫感薄片1之際，以及在溫感薄片1的使用中，不易感覺溫感薄片1的周緣部25的硬度，故溫感薄片1在初期及使用時之兩方皆佩帶感優異。 As shown in FIGS. 3 and 4, the temperature-sensitive sheet 1 has a peripheral edge portion 25 located in a region within a predetermined distance from the outer peripheral edge 23 of the temperature-sensitive sheet 1. The temperature-sensitive sheet 1 is attached to the peripheral edge portion 25 and does not have an embossed portion. This makes it difficult for the wearer to feel the hardness of the peripheral edge portion 25 of the temperature-sensitive sheet 1 when wearing the temperature-sensitive sheet 1 and during the use of the temperature-sensitive sheet 1. Therefore, the temperature-sensitive sheet 1 is both at the beginning and at the time of use. Both have excellent wearability.

溫感薄片1的肌膚抵接薄片7，係在包含周緣部25的整面，塗佈有溫感組成物(未圖示)。換言之，溫 感薄片1，係在周緣部25，包含了：含有溫感組成物(未圖示)的肌膚抵接薄片7，亦即溫感層17。藉此，溫感組成物係使佩帶者的肌膚之溫感劑所接觸的溫感劑接觸部分的瞬態受體電位通道效率良好地活化，而能夠效率良好地對於佩帶者賦予溫熱感。 The skin contact sheet 7 of the temperature-sensitive sheet 1 is attached to the entire surface including the peripheral edge portion 25 and is coated with a temperature-sensitive composition (not shown). In other words, Wen The sensory sheet 1 is attached to the peripheral portion 25 and includes a skin contact sheet 7 containing a sensory composition (not shown), that is, a sensory layer 17. Thereby, the temperature-sensitive composition system efficiently activates the transient receptor potential channel of the temperature-sensitive agent contact portion of the temperature-sensitive agent in contact with the skin of the wearer, and can efficiently give the wearer a sense of warmth.

溫感薄片1，係不含發熱劑。就含有發熱劑的溫熱薄片而言，係以使發熱劑持續接觸佩帶者的肌膚為目的，而一般而言將固定部與發熱劑配置於在溫熱薄片的厚度方向重疊的位置，故會受到發熱劑的影響，使固定部的溫度上升而固定部容易軟化。因此，在溫熱薄片的使用結束，並將溫熱薄片從衣服卸除之際，軟化了的固定部容易殘留於衣服。 The temperature-sensitive sheet 1 does not contain a heating agent. The warm sheet containing a heating agent is for the purpose of continuously contacting the heating agent with the skin of the wearer. Generally, since the fixing portion and the heating agent are arranged at positions overlapping in the thickness direction of the heating sheet, Affected by the heating agent, the temperature of the fixing portion is increased, and the fixing portion is easily softened. Therefore, when the use of the warm sheet is completed and the warm sheet is removed from the clothes, the softened fixing portion is liable to remain on the clothes.

另一方面，於溫感薄片1，因溫感薄片1本身不發熱，故溫感薄片1的固定部13不易軟化，而在溫熱薄片1的使用結束，並將溫熱薄片1從衣服21卸除之際，溫感薄片1的固定部13不易殘留於衣服21。 On the other hand, in the thermosensitive sheet 1, since the thermosensitive sheet 1 itself does not generate heat, the fixing portion 13 of the thermosensitive sheet 1 is not easily softened, and after the use of the thermosensitive sheet 1 is completed, the thermosensitive sheet 1 is removed from the clothes 21. At the time of removal, the fixing portion 13 of the temperature-sensitive sheet 1 is unlikely to remain on the clothes 21.
