ABSTRACT:
The present invention relates to a polymeric solid electrolyte which comprises a network molecule formed by polymerizing a polyethylene glycol with acrylic or methacrylic groups at both ends, and containing therein (a) a specific acrylate-type copolymer, (b) a low molecular polyethylene glycol with both ends methyl-esterified, and (c) an alkali metal salt or ammonium salt. The polymeric solid electrolyte of the present invention has an ionic conductivity of 10.sup.-5 S/cm or higher at room temperature, is strong in film strength even with a thickness of 100 .mu.m or less, and is superb in adherence to electrodes.
