Solid electrolytic capacitor and method of manufacturing solid electrolytic capacitor cathode material

摘要

A solid electrolytic capacitor comprising: an anode of valve metal or of an alloy of which main component is the valve metal; a dielectric layer formed by anodizing the anode; an electrolyte layer formed on the dielectric layer; and a cathode formed on the electrolyte layer; wherein the cathode comprises a carbon layer containing coated carbon particles in which at least a part of the surface of carbon particles is coated with metal and/or metal compound having higher conductivity than carbon.
