ABSTRACT:
An electric double-layer capacitor includes one or a group of electric double-layer capacitor element(s), an electrode structural member comprising of electrode plates and an insulating plate, stacked on the electric double-layer capacitor element(s), and a case for enclosing the electric double-layer capacitor element(s) and the electrode structural member. The case has a shelf-like stepped portion in the inner peripheral surface of its side wall. The shelf-like stepped portion and the side wall of the case are in close contact with the peripheral edge portion of the insulating plate, in order to airtightly seal the case and the insulating plate. Each electrode plate has an electrode terminal outwardly extending from the opening end portion of the case.
