PROBLEM TO BE SOLVED: To provide a gel ion conductor having high transparency, which is equipped with high electrolytic solution holding power and mechanical strength (shape maintaining characteristics against external stress).SOLUTION: The gel ion conductor contains polyurethane as a matrix material of gel, a nonaqueous solvent, and electrolyte. The polyurethane has a cross-linked structure derived from polycaprolactone polyol having at least two or more hydroxyl groups in a molecule, and a compound (wherein at least three or more of either hydroxyl group or isocyanate group are contained therein) having at least two or more isocyanate groups in a molecule. |
