Abstract
An electrolytic solution for an electric double layer capacitor is provided. A spiro compound of formula (1) is provided as an electrolyte in an aprotic solvent. The electric conductivity of the solution at -40.degree. C. is 0.85 mS/cm or higher. ##STR00001## This electrolytic solution provides a high dissolution of electrolyte in solvent and exhibits excellent conductivity and electrostatic capacity over a wide range of temperatures Further, the electrolytic solution exhibits high resistance to voltage, even under long-term high voltage load, and exhibits suppressed lowering of electrostatic capacity allowing the solution to excel in long-term stability.
