To provide an absorbent article excellent in absorbent property and hardly causing liquid leakage.
In the absorbent article 1 having an absorbent body 3 constituted by comprising an absorbent polymer 10, the liquid passing speed under a pressure of 2.0 kPa is 50 ml/min or more, the absorbing quantity under a pressure of 2.0 kPa is 25 g/g or more, the absorbing speed according to a vortex method is 30 sec or less in the absorbent polymer 10. As the absorbent polymer, one constituted by polymerizing a polymerizable polymer thereafter making a bridging structure by adding a bridging agent and further subjecting the same to surface bridging as needed, one constituted by polymerizing the polymerizable polymer and at the same time synthesizing another block polymer and bridging them each other and subjecting the same to surface bridging as needed, and one having polyamino acid as principal chains or others can be used.
