Abstract

In an electric double layer capacitor 100 comprising an electrochemical element 30 including a pair of electrode layers 32, 36; a pair of container members 10, 20 made of a metal surrounding the electrochemical element 30; and an electrically insulative gasket 40, interposed between the pair of container members 10, 20, for electrically insulating the container members 10, 20 from each other; the electrochemical element 30 is sealed by causing a crimping part 10bof one container member 10 to crimp a brim 20b of the other container member 20 while interposing the gasket 40 between the crimping part 10b of one container member 10 and the brim 20b of the other container member 20, whereas the crimping part 10b of one container member 10 and the brim 20b of the other container member 20 are bonded to each other by the gasket 40.

An electrochemical device comprising:

an electrochemical element including a pair of electrode layers;
a pair of container members made of a metal surrounding the electrochemical element;
and
an electrically insulative gasket, interposed between the pair of container members, for electrically insulating the container members from each other;
wherein the electrochemical element is sealed by causing an end part of one container member to crimp an end part of the other container member while interposing the gasket between the end part of one container member and the end part of the other container member, one of the pair of electrode layers being electrically connected to one container member, the other of the pair of electrode layers being electrically connected to the other container member;
and
wherein the end part of one container member and the end part of the other container member are bonded to each other by the gasket.
