The present invention addresses the problem of providing a novel absorbent article in which the area of contact between a top sheet and the skin of a wearer is small. In order to solve such a problem, a sanitary napkin (1) is provided with a top sheet (2), a back sheet (3), and an absorbent body (4) disposed between the top sheet (2) and the back sheet (3), wherein: the top sheet (2) is liquid-permeable sheet having: an extensible area (21) in which an extensible bellows-like section (210) is formed in a liquid supply area (20) for receiving a supply of liquid and a flexible area (22) that encloses the extensible area (21). The liquid-permeable sheet is disposed in such a manner that the bellows-like section (210) primarily extends in a secondarily extensible manner, and the extensible area (21) forms raised sections (200) that rise in the thickness direction of the sanitary napkin (1).本發明以提供頂部薄片與使用者的肌膚之接觸面積小的新穎吸收性物品為課題,為了解決該課題,具備頂部薄片(2)、背部薄片(3)、在頂部薄片(2)及背部薄片(3)間所設置的吸收體(4)的生理用衛生棉(1)中,頂部薄片(2)為具有於接受液體的供給之液體被供給區域(20)形成有可伸展的蛇腹部(210)的伸展性區域(21)、與包圍伸展性區域(21)的可撓性區域(22)之液體透過性薄片,液體透過性薄片以蛇腹部(210)可二次伸展地進行一次伸展,且伸展性區域(21)在生理用衛生棉(1)的厚度方向形成隆起的隆起部(200)之方式設置。
