A disposable absorbing wearing article in which an absorbing core is made deformable to form an absorbing barrier against excreta and to cause an absorbing chassis including the absorbing core to fit the torso of a wearer. Thus, the appearance in wear is improved and excreta leakage is prevented. The wearing article is constituted of an absorbing chassis (11) and an annular elastic waist panel (12). The absorbing chassis (11) includes an absorbing core, which has a deformation induction part (36) formed therein. This wearing article has been constituted so that at least both edges of the absorbing core are deformed toward the torso of a wearer through the deformation induction part (36) at least by the elastic shrinkage of a front waist panel (12A) as a component of the annular elastic waist panel (12).
