Claims

[Scope of Claim for Utility Model Registration] (1) A predetermined number of coin-shaped cells, which are capacitive elements, are inserted into a bottomed cylindrical exterior metal case, and a lead protrudes outward from the opening of the exterior metal case. An electrode unit in which first and second electrode plates each having a terminal are stacked with an electrically insulating plate in between is inserted into the opening of the exterior metal case so that the first electrode plate is in electrical contact with the cell. In the electric double layer capacitor, the opening of the exterior metal case is caulked inward and the edge thereof is mechanically and electrically connected to the second electrode plate. A bendable tongue piece is formed by providing a pair of parallel slits in the axial direction of the electrode unit, and an engagement groove that can be engaged with the tongue piece is provided on the electrode unit side. The electric double layer capacitor is characterized in that the tongue piece is bent inward and engaged with the engagement groove after the tongue piece is placed in the case opening. (2) The electric double layer capacitor according to claim (1), wherein the engaging groove is formed from the second electrode plate to the electrically insulating plate. (3) The electric double layer capacitor according to claim (1), wherein the engaging groove is formed in the second electrode plate. (4) In claim (1) or (2) of utility model registration, it is stated that the second electrode plate and the electrical insulating plate are connected so that no relative rotational deviation occurs between them. Characteristic electric double layer capacitor. (5) In claim (1) for utility model registration, the lead terminal of the first electrode plate includes a small hole formed in the electrically insulating plate and a groove portion formed in the second electrode plate. An electric double layer capacitor, characterized in that the capacitor is drawn out to the outside of the exterior metal case through the capacitor.
