PROBLEM TO BE SOLVED: To provide an absorbent article capable of efficiently absorbing a liquid in a crotch part and effectively suppressing the flow of the liquid in the longitudinal direction of the article. An absorbent article (1) includes an abdominal part (1A), a back part (1C), a crotch part (1B) located between the abdominal part (1A) and a back part (1C), and a surface sheet (2) having an uneven structure. There is. The topsheet 2 includes a plurality of first protrusions 71 distributed in the crotch portion 1B and a plurality of first protrusions 71 distributed in the abdomen 1A and the back 1C and different from the shape of the first protrusion 71. And two convex portions 72. The thickness of the absorbent article 1 at the position of the apex of the first convex portion 71 is larger than the thickness of the absorbent article 1 at the position of the apex of the second convex portion 72. When the topsheet 2 is viewed in a plan view, the area of each first protrusion 71 is smaller than the area of each second protrusion 72. The length in the width direction Y of the second convex portion 72 is longer than the length in the longitudinal direction X.
