Abstract
A disposable diaper includes a liquid-permeable topsheet, a liquid-impermeable backsheet and an absorbent core disposed therebetween. The core has its transversely opposite side edges curved inwardly of the core. Portions of the topsheet and the backsheet extending outward beyond the side edges of the core are put flat and bonded together. Such extensions are folded inwardly of the diaper along straight folding lines extending longitudinally outside the respective curved side edges of the core so as to form a pair of leak-proofing cuffs. First and second elastically stretchable/contractile members are bonded under appropriate tension to the respective leak-proofing cuffs along its inner side edges and the straight folding lines.
