An absorptive article has an absorptive article body, a pair of side flaps, and a pair of waist flaps provided in the rear region so as to extend outward from the side flaps in the lateral direction of the absorptive article body. Each of the pair of waist flaps has formed thereon a waist stretchable region extended so as to reach that edge of the waist flap which is on the belly side. The waist stretchable regions are adapted such that the dimension of the waist stretchable region stretched at the end thereof on the belly side in the lateral direction of the absorptive article body is greater than the dimension of the waist stretchable region stretched at the end thereof on the rear side in the lateral direction of the absorptive article body.
