Patent ID: 7113390

Claim:
A surface-mount thin-profile capacitor comprising: a metal foil as a base material, said metal foil including a metal core and a pair of etched layers covering opposite surfaces of the metal core, and said metal foil having opposite end portions that form anodes and opposite surfaces each having a center area provided with a cathode; a resist resin formed at a boundary between each anode and the cathode; and a conductive polymer layer formed by polymerization of a conductive polymer inside of and on a surface of each of the etched layers at the center area of the metal foil, the cathode being formed on a surface of the conductive polymer layers; wherein a part of the etched layers at each said boundary between each anode and the cathode is removed to form a removed portion; and wherein the resist resin is formed in each said removed portion so as to separate and isolate the conductive polymer layer from portions of the etched layers at the end portions of the metal foil that form the anodes.
