<p>Anodic valve metal foils (23), roughened and provided with dielectric layers (25), and collector metal foils (24) (metal foils for collector) are laminated alternately to cross with cathodic electroconductive polymer layers (26) therebetween. Anodic terminals (21) and cathodic terminals (22) are connected with the respective ends of the metal foils (23, 24). For the anodic valve metal foils (23), an aluminum foil with an unroughened internal bulk metal layer is used. The collector metal foil (24) is selected from the group consisting of an Al foil similar to the anodic valve metal foil (23), an Ni foil, a Cu foil, and an aluminum foil including carbon. As a result, a four-terminal capacitor to provide high capacitance, low impedance, high current-carrying capacity and less heat generation, as well as low equivalent series resistance and low equivalent series inductance, is obtained. <IMAGE></p> |
