The capacitor has a capacitor element, a tubular metallic case, an electrolyte, and a terminal plate. The case contains the capacitor element and is joined to a first electrode of the capacitor element at its inner bottom surface. The terminal plate is joined to the second electrode of the capacitor element and seals the opening of the case. At least one of the terminal plate and the case is provided with a through hole, into which a hermetic plug made of a rubber-like elastic body and having an external diameter larger than a diameter of the through hole is inserted.
