A disposable diaper includes a topsheet, a backsheet and an absorbent core therebetween. The topsheet is composed of a central sheet covering the core and a pair of side sheets lying at transversely opposite sides of the central sheet and extending longitudinally of the diaper, together with the backsheet. Each side sheet has a proximal zone bonded to the backsheet without overlapping a side edge of the central sheet bonded to the backsheet. An outer zone bonded to the remaining zone of the backsheet lying outside the proximal zone forms an elasticized first side flap and an inner zone extending above the central zone forms an elasticized second side flap.
