PROBLEM TO BE SOLVED: To suppress sticking of excrement to the buttocks due to reversion without impairing the absorbability of watery stool or the like. SOLUTION: This disposable diaper is so formed that multiple weld parts M for fixing a top sheet 30 to an intermediate sheet 40 are provided in the following ranges at a predetermined interval apart without any adhesive used for the fixing: a first range 35 within±10 mm in the width direction using width-directional both side edges of a through-hole group in a width-directional central area 31; a second range 36 within±10 mm in the width direction using width-directional both side edges of a through-hole group in a left-side area 33; and a third range 37 within±10 mm in the width direction using width-directional both side edges of a through-hole group in a right-side area 33. The width-directional central area 31, the left-side area 33 and the right-side area 33 outside the first range 35, the second range 36 and the third range 36 are not fixed to the second sheet 40.
