Abstract: The problem to be solved is to provide a nondrying polymer hydrogel, which is not dried under atmospheric conditions and has excellent mechanical properties, and a method for producing the nondrying polymer hydrogel. A nondrying polymer hydrogel having both excellent nondrying properties and mechanical properties (e.g., excellent elongation properties, compression properties, and surface adhesiveness) can be produced by using a nondrying polymer hydrogel including a deliquescent substance in such a manner that the water vapor pressure shown by the polymer hydrogel is equal to or lower than the water vapor partial pressure in the atmosphere, in particular, by allowing a deliquescent substance to be contained at a high concentration in a polymer hydrogel having a network structure formed by a polymer of a water-soluble radically-polymerizable organic monomer having a specific chemical composition and a delaminated water-swellable clay mineral.
