PROBLEM TO BE SOLVED: To provide an electric double layer capacitor contriving an improvement in high-rate characteristics and an increase in capacity, and reducing manufacturing costs, and provide its manufacturing method. SOLUTION: An electric double layer capacitor having an electrode comprises a pair of polarizable electrodes 1 and 2 provided with a carbon material respectively, and a separator 3 interposed between the polarizable electrodes 1 and 2 with the polarizable electrodes 1 and 2 and the separator 3 impregnated with an electrolyte solution. The carbon material of the polarizable electrodes 1 and 2 comprise fullerene treated with a microwave activation process and/or a carbon nanotube treated with a microwave activation process.
