PROBLEM TO BE SOLVED: To provide an absorbent article in which liquid leakage is suppressed. SOLUTION: The liquid impermeable sheet 40, the absorber 10, and the liquid permeable sheet 30 are provided, and the liquid impermeable sheet 40, the absorber 10, and the liquid permeable sheet 30 are arranged in this order. Article 100 is disclosed. The absorber 10 includes water-absorbent resin particles 10a. Formula (1): Staining index = 1-minute value of unpressurized DW (mL/g) + artificial urine permeation rate during 10-fold swelling (g/min)... Water absorption represented by (1) The bleeding index of the resin particles 10a is 10.0 or more, and the water absorption amount of the water absorbent resin particles 10a with respect to the physiological saline is 50.0 g/g or more.
