Abstract
(EN)
The purpose of the present disclosure is to provide an absorbent body for absorbent articles which has an excellent temporary liquid storing property and liquid migration property in the thickness direction. An absorbent body according to the present disclosure has the following configuration. This absorbent body (1) is an absorbent body (14) for absorbent articles which has the thickness direction (T) and the plane direction (P), the absorbent body having: a first absorbent layer (41) including an absorbent polymer; a second absorbent layer (42) including a highly absorbent polymer; and an intermediate layer (43) disposed therebetween and including a fiber, wherein the absorbent body (1) is characterized in that the intermediate layer (43) is provided with a low fibrous density part (LD) having relatively low fibrous density, and a high fibrous density part (HD) having relatively high fibrous density.
