PURPOSE:To attain a thin film electrode structure which easily increases area and to obtain an electric double layer capacitor allowing low equivalent series resistance (ESR) by filling the holes of a porous conductive film with ion conductor. CONSTITUTION:An electric double layer capacitor possesses electrolyte between electrodes facing each other, the electrodes are composed of a porous conductive film and the holes of the porous conductive film are filled with ion conductor. Since the porous conductive film has a channel which penetrates mesh structure three-dimensionally developed, the specific surface area is large and since the holes are filled with the ion conductor, resistance components regarding the ion movement is reduced. Liquid dripping is prevented and the capacitor can be treated as a solid as a whole. Thus, the increase of the area and capacitance and the reduction of the resistance are facilitated and the electric double layer capacitor having low ESR is obtained. |
