Here is disclosed a disposable diaper improved so as to give the wearer no uncomfortable feeling to wear this diaper and to allow water vapor generated as a result of sweat evaporation to be let out from the diaper through the wings. A pair of second wings attached to transversely opposite side edge portions of a rear waist region and extending outward in a transverse direction are formed from an elastically stretchable composite sheet. The composite sheet comprises a breathable stretchy plastic film formed with a plurality of air passages each extending in a thickness direction from a first opening facing the wearer's skin toward a second opening facing away from the wearer's skin and breathable heat-sealable fibrous nonwoven fabric layers partially bonded to both surfaces of the plastic film and formed with a plurality of gathers rising and falling along surfaces of the nonwoven fabric layers.
