PROBLEM TO BE SOLVED: To provide a pull-up disposable diaper capable of improving the air-permeability by reducing the basis weight of the nonwoven fabric used in the diaper and reducing the material cost while preventing fusing or strength shortage in fused parts on left and right sides of front and rear body parts. SOLUTION: In the pull-up disposable diaper, two reinforcing sheets 6 and 7 made of the nonwoven fabric are attached respectively to the left and right sides only in zones including the left and right side fused parts 5 and the vicinities of the side fused parts. The reinforcing sheets 6 and 7 are fused to the nonwoven sheet constituting the front body part 3 and the rear body part 4 to reinforce the side fused parts 5. In one embodiment, the reinforcing sheet 6 or 7 is located between a presser sheet 15 or 16 and an inner sheet 22 of a shell material 13 at a part where the left or right side fused part 5 is formed either in the front body part 3 or the rear body part 4.
