<p>PROBLEM TO BE SOLVED: To secure reliability of an electric double layer capacitor for a long period. SOLUTION: The separators 2 used in this electric double layer capacitor are composed of nonwoven fabrics or porous films containing a polyolefin resin at the weight ratio of >=10%. The separators 2 are respectively sandwiched between paired polarizable electrodes 1, and the electrodes 1 are stuck to the separators 2 by heat pressing. The stuck bodies are impregnated with an aqueous sulfuric acid solution. Around the stuck bodies, structures containing gaskets 4 and current collecting bodies 3 are alternately laminated upon another. To the current collecting bodies 3, tin-plated aluminum terminals 5 are respectively stuck with silver paste. The aluminum terminals 5 and current collecting bodies 3, the bodies 3 and electrodes 1, and the bodies 3 and gaskets 4 are respectively stuck to each other by applying pressures to the current collecting body portions and gasket portions by heat pressing.</p> |
