PROBLEM TO BE SOLVED: To provide an absorber and an absorbent article, capable of compatibly achieving a high absorption amount and a low liquid remaining amount in repetitive absorption of excretion liquid.SOLUTION: An absorber 10 has hydrophilic fibers and a water absorptive polymer, and includes a recessed part 11 with a depth of not less than 20% but not more than 100% of the thickness of the absorber. A mass ratio represented by [mass of the hydrophilic fibers]/[mass of the water absorptive polymer] in the absorber 10 is not less than 1/5 but not more than 1/0.01. The water absorptive polymer, in a swelling magnification of 60% or less, has a passage speed of artificial urine 40 g under the pressurization of 2 kPa, of 100 g/min or less.COPYRIGHT: (C)2014,JPO&INPIT【課題】繰り返しの排泄液の吸収において高吸収量と低液残り量とを両立することができる吸収体及び吸収性物品を提供すること。【解決手段】本発明の吸収体10は、親水性繊維と吸水性ポリマーとを有する吸収体であり、吸収体の厚みの20%以上100%以下の深さの凹部11を有しており、吸収体10における[親水性繊維の質量]/[吸水性ポリマーの質量]で表される質量比が1/5以上1/0.01以下であり、吸水性ポリマーは60%以下の膨潤倍率で人工尿40gの2kPa加圧下での通液速度が100g/分以下である。【選択図】図4
