The present invention relates to an absorbent article. It can prevent an area of the absorbent body forming with slots from twisted and damaged. The problem stated above can be solved by providing a pad-typed disposable diaper, which comprises a pair of slots with predetermined width forming in an area of the absorbent body in an anterior-posterior direction at least corresponding to a crotch portion, and the pair of slots with predetermined width respectively extend along the anterior-posterior direction by defining a first portion positioned on the middle of the width direction, and a second portion and third portion positioned on both side of the width direction； protruding portions protruding on both side of the width direction on the middle of the anterior-posterior direction of the first portion； and dent portions which can be used to engage with the protruding portions toward the width direction and are positioned on the anterior-posterior direction of the second portion and third portion corresponding to the protruding portions.本發明涉及吸收性物品。防止吸收體的窄縫形成區域的扭結、破裂。上述課題透過墊型一次性尿布解決，其在吸收體的至少與胯間部對應的前後方向區域形成有一對既定寬度的窄縫，該一對既定寬度的窄縫以分別劃分位於寬度方向中間的第一部分與位於該寬度方向兩側的第二部分及第三部分的方式沿前後方向延伸，在第一部分的前後方向中間，具有朝寬度方向兩側突出的突出部，在第二部分以及第三部分的與突出部對應的前後方向位置，具有供突出部朝寬度方向外側嵌入的凹陷部。
