Abstract

To provide (i) a water-absorbing agent, having a water-absorbent resin as a main component, whose absorbency is high and liquid permeability is enhanced and (ii) a production method thereof. The water-absorbing agent of the present invention includes a water-absorbent resin obtained by polymerizing an unsaturated monomer having a carboxyl group and included in an aqueous monomer solution in the presence of at least a non high molecular compound having four or more functional groups each capable of forming a covalent bond with a carboxyl group.
