To provide a pad which may be worn closely fitted with an inner surface of a disposable diaper by a total region of an absorbent body in a fore-aft direction and a width direction deformed inwardly thereof, thereby improving fit performance with respect to a wearer. The problem is solved by: forming an absorbent body with a fore part, an aft part, and a narrowed part in which a dimension in the width direction of the fore part and the aft part is reduced； forming a first depression in a central part of the absorbent body in the width direction which extends in the fore-aft direction； forming a third depression in a central part of the narrowed part in the fore-aft direction which extends in the width direction； forming a second depression in a fore-side part in the fore-aft direction in the narrowed part which extends in the width direction； and forming a fourth depression in an aft-side part in the fore-aft direction in the narrowed part which extends in the width direction.本發明所欲解決的問題在於提供一種尿片，其能夠使吸收體的前後方向與寬度方向的整個區域朝向內側變形而緊密貼合地安裝在拋棄式尿布的內表面，從而能夠提高對於穿用者的合身性。作為解決上述問題的手段，可藉由下述尿片來解決：吸收體由前身部、後身部及收攏部形成，該收攏部是使前身部與後身部縮小寬度方向的尺寸而成，在吸收體的寬度方向的中央部形成有在前後方向上延伸的第一溝，並在收攏部中的前後方向的中央部形成有在寬度方向上延伸的第三溝，在收攏部中的前後方向的前側部形成有在寬度方向上延伸的第二溝，在收攏部中的前後方向的後側部形成有在寬度方向上延伸的第四溝。
