(EN) Provided are water-absorbent resin particles having a sufficient water retention capacity and excellent in initial liquid diffusivity and liquid permeability in the antigravity direction between swollen gels. The present invention relates to a water-soluble vinyl monomer (a1) and / or a vinyl monomer (a2) which becomes a water-soluble vinyl monomer (a1) by hydrolysis, and a cross-linked polymer (A) containing a cross-linking agent (b) as an essential constituent unit. And talc (c) containing 1 to 20% by weight of aluminum oxide, the talc (c) being 0.1 to 10% by weight based on the weight of the polymer (A). Water-absorbent resin particles contained: A method for producing water-absorbent resin particles, which comprises a step of mixing the crosslinked polymer (A) and the talc (c).充分な保水量を持ち、初期の液拡散性および膨潤したゲル間の反重力方向に対する通液性に優れた吸水性樹脂粒子を提供する。本発明は、水溶性ビニルモノマー(a1)及び/又は加水分解により水溶性ビニルモノマー(a1)となるビニルモノマー(a2)、並びに架橋剤(b)を必須構成単位とする架橋重合体(A)と、酸化アルミニウムを1~20重量%含むタルク(c)とを含有する吸水性樹脂粒子であり、前記タルク(c)を前記重合体(A)の重量に基づいて0.1~10重量%含有する吸水性樹脂粒子;前記架橋重合体(A)と、前記タルク(c)とを混合する工程を含む吸水性樹脂粒子の製造方法である。
