Provided is an absorbent article in which a space that is formed in the vicinity of the width-direction side surfaces of the absorbent body of said absorbent article recovers even after collapse. In addition, the skin feel of the absorbent article is satisfactory even when the space that is formed around the width-direction side surfaces of the absorbent body is collapsed. The absorbent article has a longitudinal direction and a width direction, and comprises a liquid-permeable top sheet (2) that is provided to the skin side, a liquid-impermeable back sheet (3) that is provided to the clothing side, and a liquid-holding absorbent body (4) that is provided between the top sheet (2) and the back sheet (3). The space (42) is formed around the width-direction side surfaces (41) of the absorbent body (4) by the top sheet (2) and the width-direction side surfaces (41) of the absorbent body (4). On at least the outer side of the width-direction side surfaces (41) of the absorbent body (4), the top sheet (2) extends in the longitudinal direction and comprises first ridge fold sections (21) and valley fold sections (23) that are arranged so as to alternate in the width direction, and second ridge fold sections (22) that extend in a direction that intersects the first ridge fold sections (21).提供吸收性物品中吸收體的寬方向的側面的周邊所形成的空間即使崩散亦會回復,同時吸收體的寬方向側面的周邊所形成的空間崩散時,吸收性物品的膚觸變得良好的吸收性物品。本發明之吸收性物品,具有長度方向及寬方向,包含肌膚側所設置的液透過性的頂部薄片(2)、著衣側所設置的液不透過性的背部薄片、頂部薄片(2)及背部薄片間所設置的液保留性的吸收體,藉由吸收體的寬方向的側面及頂部薄片(2)而在吸收體的寬方向的側面的周邊形成空間,至少吸收體的寬方向的側面之外側中,頂部薄片(2)包含在長度方向延伸存在且在寬方向交互排列的第1山摺部(21)及谷摺部(23)與在與第1山摺部(1)交叉方向延伸存在的第2山摺部(22)。2‧‧‧頂部薄片21‧‧‧第1山摺部22‧‧‧第2山摺部23‧‧‧谷摺部
