Abstract: There is provided a composition for gel electrolyte that has excellent coatability, gelation properties, and liquid retention properties, has a high film strength after gelation, and can impart excellent power characteristics and a high capacity retention ratio to an electrochemical capacitor. The composition for gel electrolyte comprises an electrolyte salt and a polyether copolymer having an ethylene oxide unit, wherein the polyether copolymer has a weight-average molecular weight of 100,000 to 1,000,000, and the composition for gel electrolyte has a viscosity at 25° C. of 1 to 12 Pa·s.
