Claims

[Claims for Utility Model Registration] (1) A case having a cylindrical body with a bottom made of a conductive material, in which a plurality of electric double layer capacitor cells are placed, the lowest one of which is on the bottom surface of the case. In addition to stacking them so that they are in electrical contact,
A first terminal board having a lead piece that can protrude to the outside through the opening of the case is placed on the top of the cell stack, and an insertion hole for inserting the lead piece of the first terminal board into the bottom part. An electrical insulator in the form of a bottomed cylindrical body having a hole electrically insulates the circumferential surface of the cell stack and the first terminal plate from the case, and A laminated electric double layer capacitor in which a second terminal plate having a lead piece is arranged and the edge of the opening is caulked to bring the second terminal plate into electrical contact with the case and fix it. In the laminated electric double layer capacitor, the electric insulator is provided with guide means for coaxially positioning the second terminal plate with respect to the first terminal plate. . (2) In the utility model registration claim (1), the laminated electric double layer is characterized in that the guide means is an annular rib integrally formed along the outer periphery of the bottom of the electric insulator. Capacita.
