A solution or dispersion of an ion-permeable compound, a carbon fine particle a, and a solvent is coated on a conductive sheet such as an aluminum foil, the coat is dried to form a film a, which allows to obtain a collector for an electric double layer capacitor. A solution or dispersion of a binder, a carbon fine particle b, an activated carbon b, and a solvent is coated on the film a, the coat is dried to form a film b, which results in obtaining an electrode for an electric double layer capacitor. The electrode is piled on a separator, and immersed in an electrolytic solution to obtain an electric double layer capacitor.
