Abstract
An absorbent member () of the invention has a hydrophilic continuous fiber web () and lumpy particles of an absorbent polymer () held in the web (). The absorbent polymer () is localized in part in a planar or thickness direction of the absorbent member (). The continuous fibers in a region (M) in a planar direction of the web () where the absorbent polymer is distributed are in a state cut into a large number of staple fibers (). A method of producing an absorbent member includes the step of spreading lumpy particles of an absorbent polymer () on a continuous fiber web () and pressing the continuous fibers in part of the web () onto the absorbent polymer () to cut the continuous fibers.
