A disposable pull-on diaper 1 includes a liquid absorbent core 2, and the core 2 is joined to a topsheet 3 in front and rear waist regions 7, 8 as well as in a crotch region 8 but not joined to a backsheet 4 in the front and rear waist regions 6, 7. The topsheet 3 and the backsheet 4 are not joined to each other in their portions extending between longitudinally opposite ends of the liquid-absorbent core 2 and a peripheral edge 17 of a waist-opening 11. The diaper thus constructed prevents the core from being flexed or crooked.
