Electrolytic capacitor

The invention provides an electrolytic capacitor. The 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 cathodeconnection 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 thecathode 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. 本发明提供一种电解电容器。固体电解电容器具备：电容器元件、阳极引线框、阴极引线框、外
