Abstract: A solid electrolytic capacitor includes a capacitor element, an anode lead frame, a cathode lead frame, and an exterior member. The capacitor element includes an anode part and a cathode part. The cathode lead frame includes a cathode mount, a cathode connection part connected to the cathode mount, and a cathode terminal connected to the cathode connection part. The cathode lead frame bends in one direction at a first boundary between the cathode mount and the cathode connection part, and further bends in another direction at a second boundary between the cathode connection part and the cathode terminal. At least one of the cathode mount and the cathode terminal has a projection at an edge of the at least one of the cathode mount and the cathode terminal. The edge is at a side close to the cathode connection part. The projection projects in a first direction along which the anode part and the cathode part are aligned.

Abstract: A solid electrolytic capacitor includes a capacitor element including an anode portion and a cathode portion, an anode terminal electrically connected to the anode portion. The anode portion includes an anode body and an anode lead extending from the anode body. The anode terminal includes a first main surface and a second main surface opposite to the first main surface. The anode terminal includes a middle section, a first extension section and a second extension section, the first extension section and the second extension section being respectively disposed at both sides of the middle section. The first extension section has a first end part and is bent so that a tip of the first end part faces the second main surface. The second extension section has a second end part and is bent so that a tip of the second end part faces the second main surface. The anode lead connects with the first main surface of the anode terminal at the first end part and at the second end part.
