Abstract:
1. A method for producing a solid electrolytic capacitor, wherein a solid electrolytic capacitor element comprises an anode body composed of a material containing at least one member selected from a group consisting of an earth-acid metal, an alloy comprising an earth-acid metal as the main component, an electrically conducting oxide of an earth-acid metal and a mixture of two or more thereof; a dielectric layer formed on the anode body by electrolytic oxidation (electrochemical formation) and comprising an oxide as the main component; a semiconductor layer formed on the dielectric layer; and an electrically conducting layer stacked on the semiconductor layer; and the solid electrolytic capacitor element is subjected to molding with a resin, curing and then a voltage applying (aging) treatment, which method comprises repeating a step of leaving the resin-molded body to stand at a temperature of 225 to 305° C. and a step of aging it are sequentially repeated twice or more after the above steps of molding with resin and curing.
