PROBLEM TO BE SOLVED: To provide a high molecular electrolyte that has specific, sufficient ion conductivity, is excellent in shape retention and is easy to manufacture by forming it from acrylic rubber having a crosslinking structure, a nonaqueous solvent and an alkaline metal salt. SOLUTION: This electrolyte is a solid electrolyte having ion conductivity equal to or more than 1.0×10-4 S/cm. It is preferable that the crosslinking density of acrylic rubber having a crosslinking structure is equal to or more than 1.0×10-5 mol/cc, and a mixed solution of one, two or more kinds ofγ- lactones, esters and ethers is used as a nonaqueous solution, Cross-linking acrylic rubber prepared by forming acrylic rubber containing, as a main ingredient, alkyl acrylate and/or alkoxyalkyl acrylate into a three-dimensional form can be used as the acrylic rubber having the crosslinking structure. The acrylic rubber having the crosslinking structure can be manufactured by co-polymerizing a monomer having two or more polymerizable unsaturated groups having equivalent reactivity during polymerization, or cross-linking it by adding a cross-linking agent or the like after the polymerization. |
