摘要：
A niobium solid electrolytic capacitor having an anode composed of niobium or a niobium alloy, a dielectric layer formed on a surface of the anode by anodization and containing nitrogen and fluorine, and a cathode formed on the dielectric layer. Preferably, the dielectric layer has an increasing concentration gradient of fluorine from its cathode side toward its anode side.
