Abstract
A solid electrolytic capacitor of the present invention includes a capacitor element having an anode element, an anode lead member projecting from the anode element, a dielectric coating formed on a surface of the anode element and a surface of the anode lead member near the anode element, a solid electrolyte layer formed on the dielectric coating, and a cathode lead layer formed on the solid electrolyte layer; and an insulating enclosure member for coating the outer periphery of the capacitor element. End faces of the dielectric coating and the solid electrolyte layer formed on the anode lead member are formed approximately flush with each other. The end faces of the dielectric coating and the solid electrolyte layer are covered with an insulating layer made of a thermoplastic insulating material.
