To provide an absorbent article that can be better fitted to an excretion orifice of a wearer. An absorbent article (1) that has: an absorption body (10) that comprises liquid-absorbent fibers and has mutually orthogonal longitudinal, width, and thickness directions； and a non-skin-side sheet (30) that is arranged further to a non-skin side, in the thickness direction, than the absorption body (10). A longitudinal-direction recess (15) is formed in a width-direction center region of the absorption body (10) on the non-skin side. The recess (15) has a one-side wall part 15L on one width-direction side and an other-side wall part 15R on the other side. The recess (15) is formed such that the one-side wall part and the other-side wall part do not exert pressing force on each other when the width-direction center region of the absorption body (10) is bent such that non-skin-side surfaces of the absorbent article (1) form a 50 degree angle.[課題] 在提供可更貼合在裝設者的排泄口的吸收性物品。 [解決手段] 一種具備互相正交的長邊方向、寬邊方向、及厚度方向，並具有：具液體吸收性纖維的吸收體(10)；以及在前述厚度方向，較前述吸收體(10)被配置在非肌膚側的非肌膚側薄片(30)之吸收性物品(1)，其中，在前述吸收體(10)的前述寬邊方向中的中央區域，設有被形成在非肌膚側，沿著前述長邊方向的凹部(15)，在前述寬邊方向，前述凹部(15)，是在一方側具有一方側壁部(15L)、以及在另一方側具有另一方側壁部(15R)，前述吸收性物品(1)的非肌膚側面彼此以成為50度的角度在彎折前述吸收體(10)的前述寬邊方向的前述中央區域的狀態下，構成前述凹部(15)，而使前述一方側壁部與前述另一方側壁部成為互相不會讓擠壓力作用的狀態。
