Patent ID: 8529642

Claim:
A method for producing a solid electrolytic capacitor in which the method comprises the steps of: forming a dielectric layer in a surface of an anode body composed of a sintered body, forming a semiconductor layer composed of a conductive polymer containing a sulfur element on the dielectric layer, forming a conductor layer comprising a layer containing silver on the semiconductor layer, electrically connecting the anode body to an anode terminal and the conductor layer to a cathode terminal, respectively, sealing the thus obtained product except a portion of the anode terminal and the cathode terminal, and adjusting the content of a sulfur element in the layer containing silver of the thus produced solid electrolytic capacitor after heat history at 260° C. for 5 seconds to less than 1.3 ppm by mass, after the step of forming a layer containing silver and before the step of sealing, wherein the step of adjusting the content of a sulfur element comprises standing in an environment under reduced pressure of 6 Pa to 3,000 Pa (absolute pressure) at a temperature of 190° C. to 220° C.
