Title:
ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2021/193866
Kind Code:
A1
Abstract:
An electrolytic capacitor 100 includes a capacitor element 110 and a cathode lead terminal 130. The capacitor element 110 includes an anode body 113 and a cathode part 115. The cathode lead terminal 130 includes a connection part 133 that is connected to the cathode part 115 with a conductive member 141 therebetween. The connection part 133 includes a plate-like part 133a and first and second lateral walls rising from plate-like part 133a. A plurality of grooves 133g are formed in the surfaces of the first and second lateral walls and the plate-like part 133a. The grooves 133g include multiple first and second grooves formed so as to be connected from the plate-like part 133a over the first and second lateral walls. The conductive member 141 is disposed between one surface of the cathode part 115 and the plate-like part 133a and between the two lateral surfaces of the cathode part 115 and the first and second lateral walls.
