Description

本発明に係る吸収性物品（使い捨ておむつ１）は、着用者の身体前側と身体後側とに延びる前後方向（前後方向Ｌ）と、前記前後方向に直交する幅方向（幅方向Ｗ）と、前記着用者に向かう内方向及び前記内方向と反対側に向かう外方向を有する厚み方向（厚み方向Ｔ）と、を有し、着用者の股間部に当てられる股下域（股下域Ｓ３）を備える吸収体を備える吸収性物品であって、前記吸収体は、第１吸収層（第１吸収層１３）を含む第１吸収体（第１吸収体１０）と、前記第１吸収体よりも外方向に配置され、第２吸収層（第２中央吸収層２３、第２サイド吸収層２４）を含む第２吸収体（第２吸収体２０）と、を備え、前記第１吸収体の幅方向中央には、開口（第１吸収体開口部１０Ａ、中央開口部１３Ａ）が形成されており、前記第２吸収体の幅方向中央には、前記第２吸収体が内方向に凸に曲がることができるように形成された中央曲部（第２弾性部材２８）が設けられており、前記第２吸収体は、前記中央曲部よりも幅方向外側に配置された一対のサイド連結部（サイド連結部３１）において前記第１吸収体に連結されており、前記中央曲部は、前記前後方向及び前記幅方向の少なくとも一方に、第２吸収層を収縮させるように構成されていることを要旨とする。 The absorbent article (disposable diaper 1) according to the present invention includes a front-rear direction (front-rear direction L) extending to the wearer's body front side and rear body side, a width direction (width direction W) orthogonal to the front-rear direction, and A crotch region (inseam region S3) having an inward direction toward the wearer and a thickness direction (thickness direction T) having an outward direction opposite to the inward direction and applied to the crotch portion of the wearer. An absorbent article including an absorbent body, wherein the absorbent body includes a first absorbent body (first absorbent body 10) including a first absorbent layer (first absorbent layer 13) and an outer side than the first absorbent body. And a second absorbent body (second absorbent body 20) including a second absorbent layer (second central absorbent layer 23 , second side absorbent layer 24 ) disposed in a direction, and the width direction of the first absorbent body An opening (first absorber opening 10A, center opening 13A) is formed in the center, and the first At the center in the width direction of the absorber, a central curved portion (second elastic member 28) formed so that the second absorber can bend inwardly is provided. Are connected to the first absorber in a pair of side connecting portions (side connecting portions 31) arranged on the outer side in the width direction than the central curved portion, and the central curved portion includes the front and rear direction and the width. The gist is that the second absorbent layer is contracted in at least one of the directions.
