A disposable diaper including a liquid-absorbent pad including an absorptive core and upper and lower absorptive sheets covering upper and lower surfaces of the absorptive core, respectively. The upper and lower absorptive sheets are bonded to the upper and lower surfaces of the absorptive core by means of adhesive applied on respective inner surfaces of the upper and lower absorptive sheets, and bonded to each other by means of the same adhesive at their portions extending outward beyond longitudinally opposite ends and transversely opposite side edges of the absorptive core. The adhesive describes spirals extending longitudinally of the diaper and these spirals on upper and lower absorptive sheets transversely alternate and each pair of adjacent spirals overlap each other at their transversely opposite side edges except in the proximities of their axes.
