Abstract
A capacitor includes a capacitor element, a bottomed, cylindrical, metallic case, a metallic terminal plate, and a sealing rubber. A flange is provided along the outer circumference of the terminal plate. The flange is brought into contact with the bottom face of the sealing rubber for positioning. The case is wrung from the outside thereof so as to compress the sealing rubber. The sealing rubber has at least one of a ring-shaped top projection wall projecting between the metallic case and the terminal plate on the top face thereof, and a ring-shaped bottom projection wall projecting between the metallic case and the flange on the bottom face thereof.
