PROBLEM TO BE SOLVED: To provide an absorbent resin particle composition that can produce an absorbent article free from problems such as rash.SOLUTION: This absorbent resin particle composition comprises an absorbent resin particle (B1) and an absorbent resin particle (B2), wherein the (B1) and (B2) are absorbent resin particles including a crosslinked polymer comprising a water-soluble vinyl monomer and/or hydrolyzable vinyl monomer and a crosslinking agent as essential constituent units; the following swelling time ratio (t2/t1) of (B1) and (B2) is each 3-20; the time (t1) until the swelled volume of (B1) reaches 5 mL is 10s or more and less than 30 s; the time (t1) until the swelled volume of (B2) reaches 5 mL is 30 s or more and 120 s or less. The swelling time ratio (t2/t1) is a ratio of the time (t1) until the swelled volume reaches 5 mL and the time (t2) until the swelled volume reaches 40 mL, in a measuring method of the swelled volume in the physiological saline per 1 g of absorbent resin particles. |
