An electric double layer capacitor having a pair of polarized electrodes and an electrolytic solution capable of forming an electric double layer at the interface with the polarized electrodes, wherein the electrolytic solution contains a salt of the Formula 1 as the electrolyte and at least dimethyl carbonate as a solvent:wherein R<1 >is a n-propyl group and each of R<2>, R<3 >and R<4 >which are independent of one another, is a methyl group or an ethyl group, provided that two selected from R<1 >to R<4 >may together form a tetramethylene group, and X<-> is an anion. |
