<p>PROBLEM TO BE SOLVED: To provide an electric double layer capacitor which can keep a flame-retardant effect even after an elapse of a long time.SOLUTION: An electric double layer capacitor comprises a pair of polarizable electrodes, and a separator disposed between the paired polarizable electrodes and holding an electrolyte. The electrolyte contains a phosphoric ester amide expressed by the general formula below. (In the formula, n is 1 or 2; Rand Rrepresent, independently of each other, a straight-chain or branched alkyl group having 1-10 carbon atoms; and Rf represents a straight-chain or branched fluorine-containing alkyl group having 1-10 carbon atoms, or a straight-chain or branched alkyl group having 1-10 carbon atoms.)</p> |
