PURPOSE:To obtain an electric double-layer capacitor which is large in capacitance, low in equivalent series resistance, and excellent in shock resistance and mass-productivity, where the capacitor is used to instantaneously feed a large current. CONSTITUTION:An opening is provided to a pair of opposed surfaces of large area of a polyethylene bag-like insulating case 4 whose one side is open respectively, and a conductive rubber sheet (collector) 3 of sulfuric acid-resistance is welded to the insulating case 4 by heating. A polyethylene porous separator 2 is sandwiched in between two solid-state active carbon polarizable electrodes 1, these separator 2 and tire electrodes 1 are dipped and vacuum-impregnated with electrolyte 7, the separator 2 and the electrodes 1 impregnated with electrolyte are put into the bag-like insulating case 4, and the case 4 is sealed up by welding its open side by an ultrasonic welder for the formation of an electric double-layer capacitor cell. Furthermore, two or more electric double-layer capacitor cells are laminated to form an electric double-layer capacitor. |
