PROBLEM TO BE SOLVED: To provide an absorbent article excellent in shape retention of an absorber even when force is applied from the outside.SOLUTION: An absorbent article comprises an absorber which includes a water-absorbing resin particle (P) having a crosslinked polymer (A) having a water soluble vinyl monomer (a1) and/or a hydrolyzability vinyl monomer (a2), and a crosslinking agent (b) as the essential constitutional unit, a liquid diffusion member (B), and a gel particle shape retaining agent (C) as a cationic organic polymer (c1) having a number-average molecular weight of 1,000,000 or more. A manufacturing method of the absorbent article includes coating or spraying the gel particle shape retaining agent (C) onto the surface of the liquid diffusion member (B) previously before constituting the absorber.SELECTED DRAWING: None【課題】外部から力が加わった場合でも吸収体の形状保持性に優れる吸収性物品を提供する。【解決手段】水溶性ビニルモノマー(a1)及び/又は加水分解性ビニルモノマー(a2)並びに架橋剤(b)を必須構成単位とする架橋重合体(A)を有する吸水性樹脂粒子(P)、液拡散部材(B)並びに、数平均分子量100万以上であるカチオン性有機ポリマー(c1)であるゲル粒子保形剤(C)、を含有してなる吸収体を備える吸収性物品;吸収体を構成する前に予め、ゲル粒子保形剤(C)を液拡散部材(B)の表面に塗布又は噴霧する、上記吸収性物品の製造方法。【選択図】なし
