ABSTRACT:
A solid electrolytic capacitor of the present invention includes an anode element made of a sintered body of a valve-action metal; a dielectric coating, a solid electrolyte layer, and a cathode lead layer, sequentially formed on a surface of the anode element; and an anode lead member made of a conductive metal projecting from the anode element, the anode lead member having a base end thereof embedded in the anode element, the base end being formed such that a cross section thereof perpendicular to a direction extending inwardly of the anode element has a contour with four rounded rectangular corners.
