ABSTRACT:
An electrode for an electric double layer capacitor in which resin is used as a starting material and the manufacturing cost is low and a method of manufacturing the same are disclosed. A method of manufacturing an electrode for an electric double layer capacitor containing carbonized resin includes heating resin at a temperature equal to or higher than the temperature for finishing endothermic reaction of the resin upon melting (softening to be fluidized) of the resin and equal to or lower than the temperature for starting oxidizing reaction in an atmosphere of a pressure range of 0.01 to 10 kg/cm2, cooling the temporarily baked resin to a normal temperature and powdering it, and manufacturing a molded carbon by heating the powdered resin at a temperature equal to or higher than the temperature for starting the oxidizing reaction of the resin after pressure molding or heating the powdered resin at a temperature equal to or higher than the temperature for starting the oxidizing reaction while pressurizing the temporarily baked powder resin. The electrode contains 10% or less of the ratio of the pores each having a pore size of 20 Angstrom or more to the entire surface area of the pores of the electrode.
