<p><P>PROBLEM TO BE SOLVED: To provide a laminated electric double-layer capacitor in which spatial occupancy is reduced by devising the shape of a collector terminal and safety in handling is improved. <P>SOLUTION: A capacitor unit 1 is wrapped with an aluminum laminate film 2, and a collector terminal 3 contacting a collector plate inside a pressurizing plate 5 is partially exposed from the aluminum laminate film 2. The collector terminal 3 has such L shape as comprises a contact part 3a contacting the collector plate and a terminal part 3b which is vertical to the contact part 3a and is connected to an external circuit on the side surface of the capacitor unit. The aluminum laminate film 2 comprises a hole through which at least a part of the terminal part is exposed. The aluminum laminate film 2 is heat-welded to the terminal part 3b at the outer peripheral part of the hole. So, the collector terminal of embedded type is provided where no collector terminal 3 protrudes from the capacitor unit 1. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
