PROBLEM TO BE SOLVED: To provide an electric double-layer capacitor of small internal resistance. SOLUTION: The electric double-layer capacitor includes an element, an electrolyte impregnated in the element, and a case for housing the element and the electrolyte. The element is configured such that a pair of positive and negative electrode bodies 3 face each other and a separator 4 is interposed between them. At least one of the pair of electrode bodies 3 includes a collector 1 made of aluminum and an electrode layer 2 including a carbon material stuck to at least one of the front and the back surfaces of the collector 1, and the collector 1 includes alloy layers 1a and 1b composed of carbon and aluminum. With the configuration, contact resistance between the electrode layer 2 and the collector 1 is reduced. COPYRIGHT: (C)2010,JPO&INPIT |
