In an absorbent article in which a three-dimensional opening hole mesh sheet is combined with an air-laid absorber, body fluid on the upper surface of the three-dimensional opening hole mesh sheet can be rapidly absorbed by the absorber, and the amount of body fluid absorbed by the absorber can be increased. In a liquid-permeable front surface sheet (3), a large number of small convex portions (7) protruding to a skin side are formed, on the three-dimensional opening hole mesh sheet (3A) in which apex surfaces of the small convex portions (7) are opening holes (8), mechanical emboss processing is performed to form a large number of concave portions (9) recessed to a non-skin side, the absorber (4) is an air-laid absorber that has a five-layer structure in which an air-laid pulp non-woven fabric layer (10A), a high-absorbent polymer A layer (12), an air-laid pulp non-woven fabric layer (10B), a high-absorbent polymer B layer (13) and an air-laid pulp non-woven fabric layer (10C) are stacked sequentially from the side of the liquid-permeable front surface sheet (3) and as the high-absorbent polymer A layer (12), a high-absorbent polymer that has a high water absorption rate is used, and as the high-absorbent polymer B layer (13), a high-absorbent polymer that has a high absorption capacity is used.
