Abstract
There is described a solid polymer electrolyte containing an ionic salt in a three-dimensional crosslinked compound of a poly(vinylalkyl ether) represented by the following general formula: ##STR1## (where R is CH.sub.3, C.sub.2 H.sub.5 or CH(CH.sub.3)(C.sub.2 H.sub.5); and n is an integer of 100-2,000). The poly(vinylalkyl ether) is preferably poly(vinylmethyl ether) and crosslinked by exposure to an ionizing radiation. The solid polymer electrolyte also contains a compound that is capable of solubilizing the ionic salt.
