トップシート10は、有孔又は無孔の不織布や、多孔性プラスチックシート等で形成されている。また、このうち不織布は、その原料繊維が何であるかは、特に限定されない。例えば、ポリエチレンやポリプロピレン等のオレフィン系、ポリエステル系、ポリアミド系等の合成繊維、レーヨンやキュプラ等の再生繊維、綿等の天然繊維等や、これらから二種以上が使用された混合繊維、複合繊維等を例示することができる。さらに、不織布は、どのような加工によって製造されたものであってもよい。加工方法としては、公知の方法、例えば、スパンレース法、スパンボンド法、サーマルボンド法、メルトブローン法、ニードルパンチ法、エアスルー法、ポイントボンド法等を例示することができる。例えば、柔軟性、ドレープ性を求めるのであれば、スパンレース法が、嵩高性、ソフト性を求めるのであれば、サーマルボンド法が、好ましい加工方法となる。
バックシート11は、ポリエチレンやポリプロピレン等のオレフィン系樹脂や、ポリエチレンシート等に不織布を積層したラミネート不織布、防水フィルムを介在させて実質的に液不透過性を確保した不織布(この場合は、防水フィルムと不織布とでバックシートが構成される。)等で形成されている。もちろん、このほかにも、近年、ムレ防止の観点から好まれて使用されている液不透過性かつ透湿性を有する素材も例示することができる。この液不透過性かつ透湿性を有する素材のシートとしては、例えば、ポリエチレンやポリプロピレン等のオレフィン系樹脂中に無機充填剤を混練して、シートを成形した後、一軸又は二軸方向に延伸して得られた微多孔性シートを例示することができる。さらに、マイクロデニール繊維を用いた不織布、熱や圧力をかけることで繊維の空隙を小さくすることによる防漏性強化、高吸水性樹脂または疎水性樹脂や撥水剤の塗工といった方法により、防水フィルムを用いずに液不透過性としたシートも、バックシート11として用いることができる。
外装シート12は、吸収要素20を支持し、着用者に装着するための部分である。外装シート12は、両側部の前後方向中央部が括れた砂時計形状とされており、ここが着用者の脚を囲む部位となる。
中間シート15は、トップシート10と同様の素材で形成されている。中間シート15は、トップシート10に接合するのが好ましく、その接合にヒートエンボスや超音波溶着を用いる場合は、中間シート15の素材は、トップシート10と同程度の融点をもつものが好ましい。中間シート15に不織布を用いる場合、その不織布の繊維の繊度は2.0~5.0dtex程度とするのが好ましい。
吸収体21は、繊維の集合体により形成することができる。この繊維集合体としては、綿状パルプや合成繊維等の短繊維を積繊したものの他、セルロースアセテート等の合成繊維のトウ(繊維束)を必要に応じて開繊して得られるフィラメント集合体も使用できる。繊維目付けとしては、綿状パルプや短繊維を積繊する場合は、例えば100~300g/m2程度とすることができ、フィラメント集合体の場合は、例えば30~120g/m2程度とすることができる。合成繊維の場合の繊度は、例えば、1~16dtex、好ましくは1~10dtex、さらに好ましくは1~5dtexである。フィラメント集合体の場合、フィラメントは、非捲縮繊維であってもよいが、捲縮繊維であるのが好ましい。捲縮繊維の捲縮度は、例えば、1インチ当たり5~75個、好ましくは10~50個、さらに好ましくは15~50個程度とすることができる。また、均一に捲縮した捲縮繊維を用いる場合が多い。
包装シート22は、ティッシュペーパ、特にクレープ紙、不織布、ポリラミ不織布、小孔が開いたシート等で形成されている。ただし、高吸収性ポリマー粒子が抜け出ないシートであるのが望ましい。クレープ紙に換えて不織布を使用する場合、親水性のSMMS(スパンボンド/メルトブローン/メルトブローン/スパンボンド)不織布が特に好適であり、その材質はポリプロピレン、ポリエチレン/ポリプロピレン等を使用できる。繊維目付けは、5~40g/m2、特に10~30g/m2のものが望ましい。
立体ギャザー30のギャザーシート31としては撥水性不織布を用いることができ、また弾性伸縮部材32としては糸ゴム等を用いることができる。弾性伸縮部材は、複数本設ける他、各1本設けることができる。
ギャザーシート31とバックシート11との間に、糸ゴム等からなる脚周り弾性伸縮部材41が前後方向に沿って伸長された状態で固定されている。脚周り弾性伸縮部材41は、複数本設ける他、各1本設けることができる。
ファスニングテープ50の基材51の基部は、ホットメルト接着剤等によってギャザーシート31と外装シート12の間に固定されている。また、基材51は、不織布、プラスチックフィルム、ポリラミ不織布、紙やこれらの複合素材から形成されている。
ターゲットシート55は、ループ糸が表面に多数設けられたプラスチックフィルムや不織布等から形成されている。
伸縮シート60は、背側のエンドフラップ部EFを伸縮させて装着者の背中周りに背側のエンドフラップ部EFを密着させる伸縮シートである。図4に示すように、背側伸縮シート60は、不織布から形成された内側シート61と、不織布から形成された外側シート62と、内側シート61と外側シート62の間に設けられた前後方向に所定の間隔を隔てて幅方向に延在する複数の細長状の弾性伸縮部材63から形成されている。なお、弾性伸縮部材63は、太さ470~620dtexのゴム糸を、伸長率200~250%に伸ばして設けている。
