Abstract
A disposable diaper includes a liquid-permeable topsheet, a liquid-barrier backsheet, and a liquid-absorptive core sandwiched between these two sheets. Side flaps extend from the two side edges of the core, and have elastic parts which are longitudinally stretchable. Side wings protrude from the two sides of the front and rear waist portions. Each side wing comprises a composite of a sweat-absorptive, air-permeable layer, and a liquid-barrier, air-permeable layer.
