Patent ID: 8066783

Claim:
A solid electrolytic capacitor comprising: an anode element made of a valve-action metal sintered body; a dielectric coating provided on the anode element; a solid electrolyte layer provided on the dielectric coating; a cathode lead layer provided on the solid electrolyte layer; and an anode lead member consisting of a valve-action metal, the valve-action metal of the anode element and the valve-action metal of the anode member being the same, the anode lead member having a first end and a second end, the first end being embedded in the anode element upon sintering; the anode lead member being extended such that the second end is outside the cathode lead layer, the anode lead member being formed such that a cross section of the anode lead member perpendicular to a direction extending inwardly of the anode element has a contour of flat rectangular with four rounded corners over the entire length, and the cross section of the anode lead member being uniform over the entire length.
