Abstract
In a capacitor, a capacitor elements of which positive and negative electrodes are drawn out in reverse directions is put in a metal case, and one electrode is bonded to the inner bottom of the metal case, and other electrode of the capacitor element is bonded to the inner side, and on the surface of a terminal plate sealing the opening of the metal case, a junction part of flat plate projecting to a position higher than the metal case is provided.
Claims6
A capacitor comprising:
- a capacitor element formed so that ends of positive and negative electrodes are exposed mutually in reverse directions;
- a metal case of cylindrical shape with a bottom including the capacitor element together with an electrolyte, and having one of the electrodes of the capacitor element bonded to the inner bottom;
- and
- a terminal plate having other electrode of the capacitor element bonded to the inner side, and sealing the opening of the metal case;
- wherein a flat junction part is provided at a surface of the terminal plate so as to project higher than a height of the metal case after sealing.
