PROBLEM TO BE SOLVED: To provide an electrochemical capacitor having a high voltage characteristic. SOLUTION: The electric double layer capacitor is provided with: an electrode using poly-fluorene or its dielectric; an electrode material having electric double layer capacitance; and non-aqueous system or aqueous system electrolyte. The electric double layer capacitor has a high voltage characteristic which does not exist in a conventional one since oxidation reduction potential of n-dope of a dielectric of poly-fluorene is lower compared with conventional activated carbon and oxidation reduction potential of poly-fluorene or p-dope of the dielectric is higher compared with conventional activated carbon.
