PROBLEM TO BE SOLVED: To provide an absorbent article for increasing speed at which a liquid is diffused in an absorber.SOLUTION: An absorbent article 10 of the invention comprises: a liquid permeable surface sheet 14； a liquid impermeable rear surface sheet 12； and an absorber 13 arranged between the surface sheet 14 and the rear surface sheet 12. The absorbent article 10 comprises plural recess parts 20 which are formed by compression formation on the absorber 13, and which have two side parts 201S, 202S respectively. In the absorbent article 10, in a cross section orthogonal to a direction where the recess parts 20 extend, a cross section on one side part closer to a width direction center shaft of the absorber 13, and a cross section on the other side part, are different, out of two side parts 201S, 202S.SELECTED DRAWING: Figure 5【課題】吸収体内で液体が拡散するスピードを上げるための吸収性物品を提供する。【解決手段】本発明の吸収性物品１０は、液透過性の表面シート１４と、液不透過性の裏面シート１２と、表面シート１４と裏面シート１２との間に配置される吸収体１３と、を備える吸収性物品１０であって、吸収性物品１０は、吸収体１３に圧縮形成され、２つの側部２０１Ｓ、２０２Ｓを有する凹部２０を複数備え、凹部２０の延びる方向に直交する断面において、２つの側部２０１Ｓ、２０２Ｓのうち吸収体１３の幅方向中心軸に近い一方の側部の断面積と他方の側部の断面積とは、異なっている。【選択図】図５
