    摘要： To provide a solid electrolytic capacitor where solid electrolyte is formed at the cut end part and at the masking part to a larger thickness than in other parts, where the adhesion of the solid electrolyte formed on the valve acting metal oxide film is improved, and whereby the capacitor is highly stabilized in various basic properties such as capacitance, dielectric loss (tan &dgr;), leakage current and short circuit defective ratio and also in the reflow soldering heat resistance and moisture resistance load characteristics. These solid electrolytic capacitor can be obtained by forming electrically conducting polymer on a dielectric film by specifying time for dipping of the surface of a valve actiong metal porous body with a solution containing a monomer and with a solution containing an oxidizing agent, time for vaporization of the solvent of the solution containing a monomer, and polymerization conditions after dipping of the solution containing an oxidizing agent.
