Capacitor

A capacitor comprising:

• a capacitor element including a first electrode, a second electrode, and a separator interposed between the first electrode and the second electrode to prevent contact of the first electrode with the second electrode;
• an electrolyte impregnated in the capacitor element;
• a cylindrical case made of metal, having a bottom, accommodating the capacitor element and the electrolyte, and being connected to the first electrode;
• a metal terminal plate having a body portion and a flange portion projected from an outer peripheral surface of the body portion toward the case, and being connected to the second electrode;
• and
• a sealing rubber abutted onto the flange portion of the terminal plate, and 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,
• wherein 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 can be compressed between the outer peripheral surface of the body portion of the terminal plate and the case,
• wherein a groove having a ring shape 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 being projected into the groove,
• wherein a width of the groove is smaller than that of the drawn and grooved portion.
