Abstract:
1. A solid electrolytic capacitor comprising: a capacitor element including an anode lead-out part and a cathode lead-out part, the cathode lead-out part having a first outer surface and a second outer surface opposite to the first outer surface; an anode lead frame connected to the anode lead-out part; a cathode lead frame being entirely a flat piece member and having a first surface and a second surface opposite to the first surface, the first surface being connected to the second outer surface of the cathode lead-out part; a cathode side assistance frame connected to the first outer surface of the cathode lead-out part and the first surface of the cathode lead frame; and a resin covering the capacitor element, the anode lead frame, the cathode lead frame, and the cathode side assistance frame, wherein the cathode side assistance frame is bent in a step-like configuration, wherein the cathode side assistance frame has a cathode side first flat part, a cathode side second flat part, and a step part provided between the cathode side first and second flat parts, the step part extending from a level of the first outer surface to a level of the second outer surface, wherein the cathode side first flat part is connected to a region of the first surface of the cathode lead frame that is different from a region of the first surface of the cathode lead frame connected to the second outer surface of the cathode lead-out part, wherein the cathode side second flat part is connected to the first outer surface of the cathode lead-out part, wherein the cathode lead-out part further has a third outer surface facing the step part, the step part inclining so as to make a clearance between the step part and the third outer surface gradually larger from the level of the first outer surface to the level of the second outer surface, and wherein the second surface of the cathode lead frame is exposed from the resin.
