PURPOSE:To obtain a polymer solid electrolyte which is suitable for electrochemical devices such as a primary cell or an electrochemical sensor by using a comb-shaped polymer of a specific polyether, an alkali or alkaline earth metal salt and a solvent dissolving the salt. CONSTITUTION:(A) A comb-shaped polymer obtained by reaction of a polyether which has a structure in which the H on the one terminal OH group of the polyether is substituted with methyl or ethyl group and the H on the other terminal OH group is substituted with a group of formula I (R1 is H, methyl, phenyl) or formula II (R2 is methyl or phenyl), and bears reactive double bonds with a low-molecular monomer bearing a reactive double bond, is admixed to (B) an alkali metal or alkaline earth metal and/or an organic ammonium salt and (C) a solvent which can dissolve component B to give the subject composition.
