Problems solved by technology

[0003] However, since the vertically embossed concave portions of the absorbent body (absorbent core) described in Patent Document 1 are formed by embossing, the density of the vertically embossed concave portion portions becomes high, and the rigidity of the entire absorbent body becomes high.

Abstract

This diaper (1) is provided with a front sheet (2), a back sheet (3), and an oblong absorber (4) disposed between the two sheets (2, 3), and is provided with a liquid-permeable interlayer sheet (5) disposed between the absorber (4) and the front sheet (2). The absorber (4) has an absorbent core (41). The absorbent core (41) has a block region (411) in which a plurality of block structures (400) comprising convexities (43) of high basis weight and grooves (44) of low basis weight are disposed in the longitudinal direction spanning from a ventral section (A) to a dorsal section (B). The convexities (43) and grooves (44) of the absorbent core (41) are integrally molded, and the interlayer sheet (5) partially covers the block regions of the absorbent core, the interlayer sheet being shorter in the longitudinal direction (Y-direction) than are the block regions (411) of the absorbent core (41). The interlayer sheet (5) is disposed deviated to the ventral section (A) side of the absorbent core (41).

Description

technical field [0001] The present invention relates to absorbent articles such as disposable diapers. Background technique [0002] Conventionally, absorbent articles using a block-shaped absorbent body provided with grooves extending in the planar direction are known (see Patent Documents 1 and 2). In the absorbent body (absorbent core) included in the absorbent article described in Patent Document 1, the longitudinally embossed recesses extending from the approximately central portion in the longitudinal direction to the abdominal portion and the back portion are spaced apart in the width direction. There are multiple configurations. When such an absorber (absorbent core) is provided, the vertically embossed recesses facilitate the diffusion of body fluids, thereby improving the absorbency of body fluids during use. [0003] However, since the vertically embossed concave portions of the absorbent body (absorbent core) described in Patent Document 1 are formed by embossi...
