An object of the present invention is to provide a particulate water-absorbent resin composition and its production process, wherein the particulate water-absorbent resin composition is an enhanced one in both of the “liquid permeability” and “liquid-sucking-up property” (which have hitherto been antithetical physical properties) of the water-absorbent resin. As a means of achieving this object, a first particulate water-absorbent resin composition according to the present invention is a particulate water-absorbent resin composition comprising a water-absorbent resin (A) of a crosslinked structure obtained by polymerizing an acid-group-containing unsaturated monomer, with the composition being characterized by: having a particle size such that particles in the range of 850 to 150 μm (but not including 850 μm) account for not less than 90 weight % of the entirety; and containing a tetra- or more functional polyol (B) at least on surfaces.
