PROBLEM TO BE SOLVED: To prevent deterioration in the electrical characteristic of a solid electrolytic capacitor using as its anode a sintered body, when using its flat anodic body in order to reduce its height. SOLUTION: In this manufacturing method of a solid electrolytic capacitor, where a solid electrolyte layer made of a macromolecular organic semiconductor compound is formed through chemical polymerization on a dielectric oxide film formed on the surface of a sintered body made of a valve-action metal, the sintered body is formed into a flat rectangular parallelepiped, and after dipping the sintered body into an oxidant prior to the chemical polymerization, the minor sides of the sintered body are kept vertical to perform semi-drying processing of the oxidant.
