CAPACITOR

摘要

Provided is a capacitor to be used in an automobile or the like. The capacitor has a high sealing ability in sealing rubber thereby to suppress leakage of driving electrolyte and has a high safety even at the time of an abnormal use. The capacitor includes a capacitor element, a bottomed cylindrical metal case (1), a metallic terminal plate (2), and a sealing rubber (3). The terminal plate (2) is equipped on its outer circumference with a flanged portion (2d), and is positioned by causing its flanged portion (2d) and the lower surface of the sealing rubber (3) to abut against each other. The upper surface of the sealing rubber (3), that is throttled from the outer side of the metal case (1) so as to compress the sealing rubber (3), is provided with a ring-shaped upper protruding wall (3a) protruding between the metal case (1) and the terminal plate (2), and, on its lower surface, with a ring-shaped lower protruding wall (3b) protruding between the metal case (1) and the flanged portion (2d).
