Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce a residual monomer in a product gel, caused by the penetration of an aqueous monomer solution into a gap formed between a moving belt and a gel with the expansion of a gel, in a process for continuously producing a hydrous crosslinked polymer gel by using a moving belt. SOLUTION: A region of a gel in the course of polymerization, having a temperature of 80 deg.C or lower is provided over an area on the moving belt from a position where the start of polymerization of a monomer is observed to a distance of at least 10 am in the travel direction of the belt.
