| 摘要 |
The present invention relates to a method for producing a solid electrolytic capacitor element, comprising forming a dielectric layer by chemical formation on the surface of an electric conductor, and sequentially forming a semiconductor layer containing an electrically conducting polymer and an electrode layer on the dielectric layer, wherein after forming the semi-conductor layer, re-chemical formation is performed in an electrolytic solution using a dopant as the electrolyte to repair the dielectric layer after formation of the semiconductor layer. By using the solid electrolytic capacitor element of the present invention, a high-capacitance solid electrolytic capacitor with a good ESR value can be produced.
