ABSTRACT:
A capacitor has a bottomed outer casing housing a capacitor element therein, a lid closing the bottomed outer casing and having a pair of insertion holes defined therein, and a pair of electrode terminals mounted on the lid and connected to the extension leads. The capacitor element includes a plurality of current collectors with respective extension leads extending therefrom. Each of the electrode terminals has an insert inserted in one of the insertion holes with an insulator interposed between the insert and the lid, a flange contiguous to an end of the insert and held against a surface of the lid through the insulator, a joint projecting from the flange and connected to the extension lead, and a staked member contiguous to an opposite end of the insert and crimped over an opposite surface of the lid with the insulator interposed between the staked member and the lid. The flange has a plurality of dimples defined in a surface thereof facing the surface of the lid, the surface of the lid having a plurality of dimples defined therein. The insulator has portions pressed into the dimples of the flange and the lid by the flange which is pressed against the surface of the lid by the staked member.
