Abstract

Provided is an absorbent article which can be prevented from slipping off while securing the absorbent function of an absorbent core. A rear girth region (S2) of the absorbent article (1) has: a rear intermediate region (R12) positioned at a front portion which is separated from the rear end edge of the rear girth region by 50-80% of the total longitudinal length of the rear girth region; and a rear crotch-side region (R13) positioned at a front portion which is separated from the rear edge of the rear girth region by 80-100% of the total longitudinal length of the rear girth region. The absorbent core (50) is disposed both in the rear intermediate region and in the rear crotch-side region. In the rear crotch-side region, a rear non-stretchable region (R15) having no rear-side stretchable member (32) in a stretched state is disposed so as to overlap the absorbent core. In the rear intermediate region, rear stretchable members are continuously disposed between a pair of side joining parts (60).

Description

technical field [0001] The present invention relates to absorbent articles such as disposable diapers. Background technique [0002] There is known a pants-type absorbent article having a pair of side joining portions joining a widthwise outer portion of a front exterior body to a widthwise outer portion of a rear exterior body (for example, Patent Document 1). An elastic member that expands and contracts in the width direction is disposed on the front exterior body and the rear exterior body, and the front exterior body and the rear exterior body are fitted to the waist of the wearer. Moreover, an absorbent core is arrange|positioned in a rear side exterior body. If the elastic member is excessively shrunk in the region overlapping the absorbent core of the rear exterior body, the length in the width direction of the absorbent core cannot be ensured, and the absorption function of bodily fluids may not be ensured. Therefore, in the region overlapping with the absorbent co...
