Claim:
An absorbent article comprising wing-like flaps that are respectively disposed on both sides or a main body in which an absorber is interposed between a liquid-permeable top sheet and a liquid-impenneable back sheet and that are to be fixed to an undergarment so as to wrap around a crotch portion of the undergarment when the article is worn, wherein the wing-like flaps have a front outline extending outward from the main body and a back outline extending outward from the main body; wherein the wing-like flaps are configured so that an angle formed by a first width-direction line of the absorbent article and the back outline is larger than an angle formed by a second width-direction line of the absorbent article and the front outline and that a gravity center of the wing-like flap is located more toward the front of the undergarment than a center of a boundary line of a root of the wing-like flap and the main body; wherein the back outline is a wavelike line formed by a combination of convex curves and concave curves; and wherein for each said one or the wing-like flaps, the back outline is shaped so as to coincide with a back outline of a reversely arranged same article aligned side by side along a same straight line parallel to said width direction line so that the front edge of the main body of the absorbent article and the back edge of the main body of the reversely arranged same article are arranged along a common straight line parallel to said width direction line.
