To provide an absorber excellent in carrying property of water-absorbing resin powder, in the absorber made by fixing the water-absorbing resin powder to a base material using resin.SOLUTION: An absorber has a base material and water-absorbing resin powder fixed to the base material by an adhesive agent. The base material is a fiber base material whose basis weight is 10 g/m-500 g/m. The adhesive agent is a copolymer which has a structural unit (X) derived from at least one kind of monomer selected from a group composed of olefin and vinyl aromatic group, and a structural unit (Y) derived from an acidic group-containing monomer, and has an acid value of 20 mgKOH/g-150 mgKOH/g.SELECTED DRAWING: None 【課題】樹脂を用いて吸水性樹脂粉末を基材に固着してなる吸収体において、吸水性樹脂粉末の担持性に優れた吸収体を提供する。【解決手段】吸収体は、基材と、この基材に固着剤によって固着された吸水性樹脂粉末とを有し、前記基材が、目付けが１０ｇ／ｍ2〜５００ｇ／ｍ2である繊維基材であり、前記固着剤が、オレフィンおよびビニル芳香族よりなる群から選択される少なくとも一種のモノマーに由来する構造単位（Ｘ）と酸性基含有モノマーに由来する構造単位（Ｙ）を有し、酸価が２０ｍｇＫＯＨ／ｇ〜１５０ｍｇＫＯＨ／ｇである共重合体であることを特徴とする。【選択図】なし
