PROBLEM TO BE SOLVED: To provide a disposable diaper hardly causing peeling and moving of an elastic member even when gas permeability and texture of side areas are improved by reducing an amount of adhesive for fixing leg-part elastic members.SOLUTION: A diaper 1 includes a first side area S1 and a second side area S2 comprising a laminated structure of a plurality of sheets, located respective side parts in the width direction of a crotch part. The side areas S1 and S2 include first and second leg-part elastic members 71 and 72 extending along side edges T1 and T2, located between the plurality of sheets 31 and 32. In the side areas S1 and S2, the two sheets 31 and 32 sandwiching the leg-part elastic members 71 and 72 are joined with each other with adhesive of 1.25 g/mor less. Further, in the side areas S1 and S2, the two sheets 31 and 32 sandwiching the leg-part elastic members 71 and 72 are intermittently fused along an extension direction of the elastic members 71 and 72, at a position adjacent to the elastic members 71 and 72.
