Abstract
An absorbent composition is produced by drying a mixture obtained by mixing a micro-filler (B) with a hydrogel having a water absorptive resin (A) and water. The hydrogel is produced by performing polymerization to produce the resin (A) and not drying the resin (A) after the polymerization. The absorbent composition has a specific surface area at least 10% lager than that of a reference composition produced by drying the hydrogel without the micro-filler (B).
