PROBLEM TO BE SOLVED: To provide a highly flexible absorber in which generation of warp is suppressed.SOLUTION: An absorber 16 has a base material sheet 12 and an absorbent core 14. The absorbent core 14 contains a water-absorbing resin, a non-fibrous water-soluble polymer, and a polyhydric alcohol. The water-absorbing resin is contained as much as 40 mass% or more and 95 mass% or less to the absorbent core. The non-fibrous water-soluble polymer is contained as much as 0.1 mass% or more and 5 mass% or less to the water-absorbing resin. The polyhydric alcohol is contained as much as 300 mass% or more and 1,500 mass% or less to the non-fibrous water-soluble polymer.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】柔軟性が高く、反りの発生が抑制された吸収体を提供すること。【解決手段】吸収体16は基材シート12及び吸収性コア14を有する。吸収性コア14は、吸水性樹脂、非繊維状の水溶性高分子及び多価アルコールを含む。吸水性樹脂は、吸収性コアに対して40質量%以上95質量%以下含まれる。非繊維状の水溶性高分子は、吸水性樹脂に対して0.1質量%以上5質量%以下含まれる。多価アルコールは、前記非繊維状の水溶性高分子に対して300質量%以上1500質量%以下含まれる。【選択図】図1
