Title
(EN) Absorbent body for absorbent article and adsorbent article
(ZH) 吸收性物品用的吸收体以及吸收性物品
Abstract
(EN)
The invention provides an absorbent body for an absorbent article having excellent adhesion, wearing properties, and absorbency, and an absorbent article. The absorbent body (14) is characterized by being provided with an intermediate layer (43) and an absorbent core (47) containing a highly water-absorbing polymer in the thickness direction (T), and is divided in the width direction (W) in a crotch region (MA) into an absorbent core overlapping region (C2OP) overlapping the absorbent core in the thickness direction and a pair of absorbent core non-overlapping regions (C2NP) that cannot not overlap the absorbent core in the thickness direction and is disposed at both ends of the absorbent core overlapping region. The absorbent body is also characterized in that the intermediate layer is provided with an intermediate layer overlapping portion (43OP) disposed in the absorbent core overlapping region and a pair of intermediate layer non-overlapping portions (43NP) disposed in the pair ofabsorbent core non-overlapping regions in the crotch region, and in the crotch region, the average unit area weight or thickness of each of the pair of intermediate layer non-overlapping portions is smaller than the average unit area weight or thickness of the intermediate layer overlapping portion.
