Abstract
A capacitor has a capacitor element, an electrolyte, a cylindrical case made of metal and having a bottom, a metal terminal plate, and a sealing rubber. The terminal plate has a body portion and a flange portion projected from an outer peripheral surface of the body portion toward the case. The sealing rubber is abutted onto the flange portion of the terminal plate, and is interposed between the outer peripheral surface of the body portion of the terminal plate and a side surface of the case for sealing the case. The case has a drawn and grooved portion formed by being drawn and thus grooved from an outside of the side surface at a place so that the sealing rubber is compressed between the outer peripheral surface of the body portion of the terminal plate and the case. Then, a ring-like groove is provided on the outer peripheral surface of the body portion of the terminal plate at a portion, which is padded with the sealing rubber, the sealing rubber is projected into the groove.
