Claims

[Scope of claim for utility model registration] (1) A predetermined number of coin-shaped capacitor cells are housed in a bottomed cylindrical metal exterior case, and
A sealing body having an electrically insulating plate interposed between an inner electrode plate and an outer electrode plate is disposed within the opening of the outer case so that the inner electrode plate is in contact with one electrode surface of the capacitor cell, and , an electric double layer capacitor in which the opening edge of the outer case is caulked inward so as to contact the peripheral edge of the outer electrode plate, and a predetermined portion of the sealing body has a cylindrical member attached to the inner wall surface of the outer case. An electric double layer capacitor characterized in that an electric double layer capacitor is formed with a rotation prevention means that is frictionally engaged with each other. (2) In the utility model registration claim (1), the electric double layer capacitor is characterized in that the rotation prevention means is formed of a plurality of protrusions formed on the peripheral end surface of the sealing body. (3) In claim (1) or (2) of utility model registration, the rotation prevention means is an electric double layer capacitor provided on the outer electrode plate. (4) In claim (1) or (2) of utility model registration, the rotation prevention means is an electric double capacitor provided on the electrical insulating plate.
