Abstract
An arrangement of a disposable diaper in which there are provided elastic members extending not only along opposite side edges of an opening formed in a skin-contacting topsheet but also further extending beyond longitudinally opposite ends of the opening substantially to longitudinally opposite ends of the skin-contacting topsheet so that the opening may sufficiently rise up together with the skin-contacting topsheet to assure reliable introduction of excretions through this opening into a pocket space defined between the skin-contacting topsheet and a separately provided topsheet underlying the skin-contacting topsheet.
