Claims

[Claims for Utility Model Registration] (1) At least one electric double layer capacitor unit 1 is made of a metal cap 2, a packing 4
, sealed using a metal container 3, and one electrode terminal 6
A and the other electrode terminal 7a are pulled out from the same direction, one electrode plate 6 having the one electrode terminal 6a is brought into contact with the upper surface of the upper plate part 2a of the cap 2, and the other electrode plate 6 having the other electrode terminal 7a is brought into contact with the upper surface of the upper plate part 2a of the cap 2. In the electric double layer capacitor in which the electrode plate 7 is brought into contact with the tip 3a of the open end of the metal container 3, a hole 5c is provided on the upper plate part 2a of the cap 2 and through which the one electrode terminal 6a passes. and a recess 5d for accommodating the one electrode plate 6, and a thin part 5b around the thick part 5a, on which the other electrode plate 7 is arranged. The thin part 5b of the insulating plate 5, which insulates the cap 2 and the one electrode plate 6 and the other electrode plate 7, is bent in such a manner that its substantially central part protrudes upward. An electric double layer capacitor characterized in that the thin wall portion 5b has spring properties. (2) The cap 2 has a protrusion 2c that protrudes upward on the outer periphery of the upper plate 2a, and the insulating plate 5
The electric double layer capacitor according to claim 1, which has a rising portion 5f at its outer peripheral end.
