The present invention aims to provide a disposable wearing article improved so that a collapse-resistant pocket can be formed in the rear waist region, bodily waste can be absorbed even in the barrier as well as in the pocket and lead of bodily waste beyond the rear end portion can be reliably prevented.In a disposable wearing article (10B), an area (21) of a rear waist region (16) in which a core (20) is present is divided into a first area (22) and a second area (23). The core (20) lying in the transversely opposite side portions (50) of the second area (23) is partially cut off to form a pair of notches (51) which are concave inward as viewed in the transverse direction of the article. A transverse flexural stiffness of the core (20) lying in the second area (23) is lower than a transverse flexural stiffness of the core (20) lying in crotch region (15) and the first area (22), and proximal portions (34) of leak-barrier sheets (19) and longitudinal ends (37) of elastic members (36) are laid on the first area (22). In the article 10B, the first area (22) lies above the crotch region (15) in a thickness direction of the article (10B) and the second area (23) forms a barrier (48) and a pocket (49).
