This disposable diaper (1) is provided with an absorbent body (2) comprising an absorber (23) and a surface sheet (21). The diaper (1) is equipped with a waist part. The waist part is divided into a ventral section (F) and a dorsal section (R). The dorsal section (R) has, as constituent sheets thereof, a hydrophobic sheet (31E) covering a dorsal end portion (2R) of the absorbent body (2) and a sweat-absorbent sheet (10) disposed on the skin-facing side of the hydrophobic sheet (31E). In a region (Q) where the sweat-absorbent sheet (10) and the absorbent body (2) overlap in the thickness direction, the bonding strength in a first bonding region (7U) where the sweat-absorbent sheet (10) and the hydrophobic sheet (31E) are bonded is greater than the bonding strength in a second bonding region (7D) where the hydrophobic sheet (31E) and the surface sheet (21) are bonded.
