Disclosed is an absorbent body (30) that comprises fiber sheets (31, 32) and a water-absorbent polymer (11) having centrifugal retention, according to JIS K 7223, of at most 20 g/g. The water-absorbent polymer (11) and the fiber sheets (31, 32) are adhered to each other by means of an anionic or non-ionic binder. Said anionic binder is preferably an anionic macromolecule obtained by polymerizing an acid-group-containing unsaturated monomer, and the non-ionic binder is preferably a non-ionic macromolecule that has a cyclic group.
