Abstract

A superabsorbent polymer includes polymer particles, surface cross-linking agents and particles made of silicon-containing inorganic salt. The polymer particles have cross-linking inside the polymer particles. The surface cross-linking agents are covalently bound to the surface of the polymer particles so as to constitute a surface cross-linked region at the surface of each said resin particle, and the particles made of silicon-containing inorganic salt cover the surface of the polymer particles.
