ABSTRACT:
Provided is a solid electrolytic capacitor including a capacitor element, an internal anode lead extending from a substantially central portion of one lateral surface of the capacitor element, other surfaces of the capacitor element normal to the lateral surface being adapted to serve as cathode terminal walls, an external anode lead connected to the internal anode lead, an external cathode lead connected to one of the cathode terminal wall, and a resin mold encapsulating the capacitor element as well as connecting portions associated therewith, wherein the external anode lead connected to the internal anode lead is bent to have at least two steps at its end portion, a lower step of said at least two steps being fixed to another one of the cathode terminal walls through an insulating material, an upper step of said at least two steps being fixed to the internal anode lead. The solid electrolytic capacitor prevents the capacitor element thereof from being displaced and the leads thereof from breaking, allows an easy assembling operation, and contributes to the down-scaling of a capacitor.
