Solid electrolytic capacitor and manufacturing method for the same

摘要

A solid electrolytic capacitor has an anode terminal and a cathode terminal for external electrical connection that are formed on one surface of a plate-like or foil-like anode member, and a cathode conductor layer formed such that it covers the area of the one surface of the anode member except for the portion where the anode terminal is secured. A first metal plate or metal foil functioning as the cathode terminal is closely joined to the one surface of the cathode conductor layer so as to cover the one surface of the cathode conductor layer. A second metal plate or metal foil is closely joined to the other surface of the cathode conductor layer so as to cover the other main surface of the cathode conductor layer. The first metal plate or metal foil and the second metal plate or metal foil function to intercept the ventilation between the anode member and the outside.
