To provide an absorbent article with improved adhesion at a heat-seal part which restricts discomfort that the heat-seal part can give a wearer and can keep fitting the wearer's skin reliably while maintaining excellent touch.SOLUTION: An absorbent article 1 includes: a liquid-permeable top sheet 2 including water-retaining fibers； a liquid-impermeable back sheet 3； an absorber 4 arranged between the top sheet and the back sheet； and a second sheet 5 which is arranged between the top sheet and the absorber and contains thermoplastic resin fibers. A heat-seal part 11 which bonds at least the top sheet and the back sheet by heat-seal is serially provided along a peripheral edge of the absorbent article. The absorbent article is divided into an inner region 1i located inside in a width direction W of the absorbent article and an outer region 1o located more outside in the width direction than the inner region. Rigidity of a heat-seal part 11o located in the outer region is lower than rigidity of a heat-seal part 11i located in the inner region.SELECTED DRAWING: Figure 1【課題】優れた肌触りを維持しつつ、熱融着部分における接合性をより高め、熱融着部分が着用者に与えうる不快感を制限し、しかも着用者の肌により確実にフィットし続ける、吸収性物品を提供する。【解決手段】吸収性物品１は、保水性繊維を含む、液透過性のトップシート２と、液不透過性のバックシート３と、トップシートとバックシートとの間に配置された吸収体４と、トップシートと吸収体との間に配置され、熱可塑性樹脂繊維を含む、セカンドシート５と、を備える。少なくともトップシートとバックシートとを熱融着により互いに接合する熱融着部分１１が、吸収性物品の周縁に沿って連続的に設けられている。吸収性物品が、吸収性物品の幅方向Ｗの内側に位置する内側領域１ｉと、内側領域よりも幅方向外側に位置する外側領域１ｏとに区分される。外側領域内に位置する熱融着部分１１ｏの剛性が、内側領域内に位置する熱融着部分１１ｉの剛性よりも低い。【選択図】図１
