An absorptive article (1A) has a rear region (S1), a crotch region (S2), and a belly region (S3) which are arranged in this order in the longitudinal direction (L) from the rear side (Ba) to the belly side (Fr). The absorptive article (1 A) is provided with an absorptive article body (2), a pair of side flaps (10), and a pair of waist flaps (20) provided in the rear region (S1) so as to extend outward from the side flaps (10) in the lateral direction (W) of the absorptive article body. Each of the pair of waist flaps (20) has formed thereon an waist stretchable region (23) extended so as to reach that edge of the waist flap (20) which is on the belly side (Fr). The waist stretchable regions (23) are adapted such that the dimension of the waist stretchable region (23) stretched at the end thereof on the belly side (Fr) in the lateral direction (W) of the absorptive article body (1 A) is greater than the dimension of the waist stretchable region (23) stretched at the end thereof on the rear side (Ba) in the lateral direction (W) of the absorptive article body (1 A).
