ABSTRACT:
An electrolytic solution for an electric double layer capacitor comprising a quaternary ammonium salt in a mixed solvent containing ethylene carbonate and propylene carbonate as an electrolyte. The electrolytic solution for electric double layer capacitor has a low coefficient of viscosity, has an excellent low temperature characteristics of not coagulating at a low temperature, possesses high electrical conductivity over a wide temperature range, and has a long-term reliability.
