ELECTRIC DOUBLE LAYER CAPACITOR

摘要

PURPOSE:To prevent the capacitor cell from being damaged by edges of the elastic body and thereby to provide an electric double-layer capacitor high in reliability and easy in caulking by installing the elastic body between the caulking section of a metallic case and a second electrode. CONSTITUTION:An elastic body 11 mounted between the caulking section 12 of a metallic case 9 and a second electrode 6 is formed to a ring shape that a surface is inclined. Accordingly, the damage of a capacitor cell 1 can be prevented, and caulking pressure can be brought to proper pressure easily.
