To provide an absorbent article capable of achieving both of high adhesion to an excretion port of a wearer and good wearing feeling.SOLUTION: The absorbent article comprises a top sheet disposed on a skin side of a wearer, a back sheet disposed on a non-skin side, and an absorber having an absorbent core and disposed between the top sheet and the back sheet, and has a longitudinal direction corresponding to the front/back direction of the wearer and a lateral direction orthogonal to the longitudinal direction. The absorbent core includes: a front core portion and a back core portion located at both ends in the longitudinal direction； an intermediate core portion located between the front core portion and the back core portion and constricted to be narrower than the front core portion and the back core portion； and a central external force buffer portion that is formed at least in the lateral center portion of the intermediate core portion and extends in the longitudinal direction.SELECTED DRAWING: Figure 1【課題】着用者の排泄口への高い密着性と良好な装着感を両立させることが可能な吸収性物品に関する。【解決手段】上記吸収性物品は、着用者の肌側に配置された表面シートと、非肌側に配置された裏面シートと、吸収性コアを有し上記表面シート及び上記裏面シートの間に配置された吸収体と、を備え、着用者の前後方向に対応する縦方向及び上記縦方向に直交する横方向を有する。上記吸収性コアは、上記縦方向の両端部側に位置する前方コア部及び後方コア部と、上記前方コア部及び上記後方コア部の間に位置し、上記前方コア部及び上記後方コア部よりも幅狭に括れた中間コア部と、少なくとも上記中間コア部の上記横方向中央部に形成され、上記縦方向に延在する中央外力緩衝部と、を有する。【選択図】図１
