An absorbent article has an absorber disposed between a permeable front surface sheet and a rear surface sheet of a non-woven fabric; wherein the front surface sheet is provided with ridged convex portions continuing in the longitudinal direction of the absorbent article at a specified interval in the width direction of the absorbent article, and provided with dot-like concave embossments at the right side adjacent position and the left side adjacent position alternately at an interval in the longitudinal direction of the absorbent article on the both sides of each of the convex portions, and the concave embossments are arranged in a zigzag pattern as a whole. The convex portion is an inclined surface having a relatively steep gradient on one side and a relatively gentle gradient on the other side, and the cross-sectional shape of the convex portion is an asymmetrical shape.
