Abstract
There is provided an electrolytic solution which may significantly improve performance deterioration with time of an electrochemical capacitor. There is provided an electrolytic solution, comprising an electrolyte salt (A) shown as the following formula (1). In the formula, “R1,” “R2,” and “R3” independently represent an alkyl group having a carbon number of 1 to 3, “R4” and “R5” independently represent hydrogen atom or an alkyl group having a carbon number of 1 to 3, and “X−” represents a counterpart anion.
