Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a water-containing material giving a water-containing gel having little shape change with temperature and low turbidity. SOLUTION: The water-containing material is produced by polymerizing a monomer composition containing 99.0-99.9 wt.% 2-hydroxyethyl methacrylate and 0.1-1.0 wt.% monomer having at least two polymerizable groups based on the total weight of the monomer composition.
