Patent ID: 7843680

Claim:
A capacitor comprising: a capacitor element including first and second electrodes constituting a pair of electrodes, and a separator intervening between the first and second electrodes, wherein the first and second electrodes are rolled together with the separator so that the capacitor element is formed such that the first and second electrodes are shifted relative to one another in opposite directions, and wherein each of the first and second electrodes comprises a polarized electrode layer formed on a current collecting unit made of aluminum foil; a cylindrical metal housing having a bottom and accommodating the capacitor element and driving electrolyte; and a terminal plate sealing an opening of the metal housing and including an inlet opening for the driving electrolyte; wherein the terminal plate includes an insulating resin portion and an electrically conductive terminal slip, the terminal slip including a terminal for external connection and a rib to be coupled to the first electrode, said insulating resin portion and said terminal slip together constituting a unitary insert-molded member forming said terminal plate; wherein the first electrode constitutes one of an anode and a cathode and is coupled to the rib of the terminal slip, and the second electrode constitutes the other of the anode and the cathode and is coupled to an inner face of the bottom of the metal housing, so that one of the anode and the cathode is brought out through the terminal of the terminal slip for external connection and the other of the anode and the cathode is brought out through the metal housing.
