• wherein the wing-shaped flap is formed with a front side outline which is extended outward from the main body part, a back side outline which is extended outward from the main body part and a tip end side outline which connects the front side outline and the back side outline,
• the tip end side outline includes a tip end side outline front portion which is extended outward from the front side outline and a tip end side outline back portion which is extended outward from the back side outline, an intersection between the tip end side outline front portion and the tip end side outline back portion forms an outermost side end portion in a width direction of the wing-shaped flap and is located on a front side with respect to a center point of a length between an end portion of the front side outline and an end portion of the back side outline in a longitudinal direction of the absorbent article, and when it is assumed that a length in the longitudinal direction of the absorbent article between the end portion of the front side outline and the outermost side end portion in the width direction is a and a length in the longitudinal direction of the absorbent article between the end portion of the back side outline and the outermost side end portion in the width direction is b, the outermost side end portion in the width direction is provided in a position where a:b is 1:1.5 to 1:3,
• the front side outline is formed with a wavy line made of convex curves and concave curves, and a section from an apex portion of the convex curve provided outermost to the outermost side end portion in the width direction of the wing-shaped flap is the tip end side outline front portion, the tip end side outline front portion being formed with a curved line which is bulged outward,
• the back side outline is formed with a straight line, and a section from the end portion of the back side outline to the outermost side end portion in the width direction of the wing-shaped flap is the tip end side outline back portion, the tip end side outline back portion being formed with a curved line which is bulged outward.
