ABSTRACT:
The present invention relates to a method for producing a niobium-oxide solid electrolytic capacitor having an anode being at least one member selected from niobium monoxide, niobium and an alloy mainly comprising niobium, or a mixture of niobium monoxide with niobium or an alloy mainly comprising niobium, which capacitor formed by the electrolytic oxidation (electrochemical formation) of the anode; and the method including sequentially repeating twice or more a step of exposing a dielectric layer to a temperature to 1,000° C. before formation of a cathode and a step of re-electrochemically forming the dielectric layer. The niobium solid electrolytic capacitor obtained by the present invention improved in the leakage current value after mounting and excellent in reliability.
