Document Type and Number:
WIPO Patent Application WO/2022/181668
Kind Code:
A1
Abstract:
Disclosed is an electrolytic capacitor comprising a plurality of anode bodies and a plurality of cathode bodies, a plurality of anode tabs (22) connected to the plurality of anode bodies, and an anode lead member connected to the plurality of anode tabs (22). The plurality of anode tabs include a first anode tab group including the anode tabs (22) and a second anode tab group including anode tabs. Each of the first anode tab group and the second anode tab group has a through hole Ha. The anode lead member includes a planar anode connecting portion (41) of metal overlying and connected to the first anode tab group and to the second anode tab group. The first anode tab group and the second anode tab group are fixed and connected to the anode connecting portion by means of a first fixing structure. The first fixing structure is formed by a part of the anode connecting portion extending through the through hole Ha and expanding so as to form a staking structure on the other side.
