Provided is an aqueous liquid absorbent resin particle that does not block the aqueous liquid absorbent resin regardless of the working environment and climatic conditions, and has excellent absorption performance under load and powder feedability. The present invention provides a water-soluble vinyl monomer (a1) and / or a crosslinked polymer (A) having a vinyl monomer (a2) that becomes a water-soluble vinyl monomer (a1) by hydrolysis and a crosslinking agent (b) as essential constituent units. The surface cross-linking agent (c) that includes at least two surface cross-linking steps for cross-linking the surface of the resin particles (B) to be contained with the surface cross-linking agent (c) is different in the first surface cross-linking step and the second surface cross-linking step. It is the aqueous liquid absorptive resin particle (P) obtained by the manufacturing method to be used.作業環境や気候条件によらず水性液体吸収性樹脂がブロッキングせず、荷重下での吸収性能や粉体フィード性に優れる水性液体吸収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）を含有する樹脂粒子（Ｂ）の表面を表面架橋剤（ｃ）で架橋する表面架橋工程を少なくとも２工程含み、１回目の表面架橋工程と２回目の表面架橋工程で異なる表面架橋剤（ｃ）を用いる製造方法で得られた水性液体吸収性樹脂粒子（Ｐ）である。
