An electric double layer capacitor having excellent self-discharge characteristics and reliability is provided. In an electric double layer capacitor having a pair of polarizable electrodes and an electrolytic solution for forming an electric double layer at the interface between the polarizable electrodes, the electrolytic solution is fluorobenzene represented by formula 1 (formula 1 Wherein n is an integer of 1 to 6.) An electric double layer capacitor comprising an organic electrolyte solution. The electrolyte used for the organic electrolyte preferably has one or more cations selected from the group consisting of Formula 2, Formula 3, and Formula 4. [Chemical 1] [Selection figure] None |
