PROBLEM TO BE SOLVED: To provide a reliable solid electrolytic capacitor having a good leakage current (LC) value after packaging. SOLUTION: A solid electrolytic capacitor has a positive electrode (which is made of a material including at least one of the following: an earth acid metal; an alloy that mainly consists of an earth-acid metal; a conductive oxide of an earth-acid metal; and a mixture of at least two of the above-mentioned items), a dielectric layer that mainly consists of an oxide formed by electrolytic oxidation (chemical conversion) of the positive electrode, a semiconductor layer formed on the dielectric layer, and a conductor layer formed on the semiconductor layer. In a manufacturing method, in which the solid electrolytic capacitor is sealed with resin and cured and then is subjected to voltage application (aging), a process of leaving the solid electrolytic capacitor, which has been sealed with resin and cured, at a temperature between 225°C and 305°C and the subsequent process of aging it are repeated twice or more.
