Abstract
A disclosed electrolytic capacitor includes a capacitor element and a cathode lead terminal. The capacitor element includes an anode body and a cathode part. The cathode lead terminal includes a connection part that is connected to the cathode part via a conductive member. The connection part includes a plate-shaped part, and first and second side walls standing from the plate-shaped part. Grooves are formed in a surface of each of the plate-shaped part and the first and second side walls. The grooves include first grooves and second grooves that are formed so as to extend continuously from the plate-shaped part across the first and second side walls. The conductive member is disposed between one surface of the cathode part and the plate-shaped part, and between two side surfaces of the cathode part and the respective corresponding first and second side surfaces.
