Abstract: Provided is an electrolytic capacitor including: a capacitor element including an anode body, a dielectric layer formed on the anode body, a solid electrolyte layer formed on the dielectric layer, and a cathode layer formed on the solid electrolyte layer; lead terminals each connected to the anode body and the cathode layer; and a packaging member covering at least part of the capacitor element. The packaging member includes a side wall that is electrically conductive, and a bottom face, with at least one of the lead terminals partially exposed from the bottom face. An insulating member is interposed between a first end of the side wall and the lead terminal exposed from the bottom face, the first end being near the bottom face.

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.
