Provided is a disposable diaper (1) which includes an absorbent member (4) and a topsheet (2). The topsheet (2) includes a first sheet (20) and a second sheet (21). Both sheets (20) and (21) are partially joined to form a plurality of joined regions (22), and the first sheet (20) has a plurality of projections (23) which protrude from the second sheet (21) toward the wearer's skin side at a portion other than the joined regions (22). The projections (23) include first projections (23A) and second projections (23B) and, when the topsheet (2) is viewed in a plan view, a second projection region (23R) is formed which includes the second projections (23B) surrounded by the plurality of first projections (23A). When the topsheet (2) is viewed in a plan view, the joined regions (22) include an inner joined region (22A1) in the second projection region (23R).

The present disclosure invention relates to a disposable absorbent article (100) comprising a liquid-pervious topsheet (10), a liquid-impervious backsheet (20) and an absorbent assembly (30) between the topsheet (10) and the backsheet (20). The absorbent assembly (30) comprises an absorbent core (40), an upper core wrap (50) and a lower core wrap (60). The absorbent core (40) comprises at least two cavities (70) free of absorbent material wherein the upper core wrap (50) and the lower core wrap (60) are permanently attached to each other, said cavities (70) being interconnected via at least one connecting line (80) comprising absorbent material. The absorbent core (40) has a first basis weight in the zone out of the cavities (70) and the connecting lines (80) and a second basis weight in the connecting lines (80), the first basis weight being greater than the second basis weight. in the cavities (70). The resulting absorbent assembly (30) may show all together a very good integrity, a very good distribution of fluids and a quick rate of absorption.

An absorbent article has a liquid-permeable front surface sheet, a liquid-impermeable back surface sheet, and an absorber disposed between the front surface sheet and the back surface sheet. The absorbent article includes a groove portion entirely or partly composed of a recessed portion, the recessed portion being formed on the front surface sheet side of the absorbent article by integrally joining the front surface sheet and the absorber together, and a flat portion enclosed by the groove portion. A diameter of a maximum inscribed circle inscribed in the flat portion is at least five times and at most 20 times as large as a width of the groove portion along a radial direction of the maximum inscribed circle.
