CAPACITOR AND MANUFACTURING METHOD THEREFOR

WIPO Patent Application WO/2024/034640

A1

The purpose of the present disclosure is to provide a stitching connection structure suited to cathode foil that includes a carbon layer, for example.　Cathode foil (6) includes base-material foil (12) and a carbon layer (14) formed onto the base-material foil, and has a through hole (18). A lead terminal (4) includes: a flat section (32) that is carried on a terminal-carrying surface of the cathode foil; and a terminal strip (34) that is formed on the flat section and that passes through the through hole and is led out to the surface on the opposite side from the terminal-carrying surface of the cathode foil and is folded over. The lead terminal is connected to the cathode foil by the cathode foil being sandwiched between the flat section and the terminal strip. The cathode foil has, at a tip-end portion of a foil strip (20) extending from an edge portion (22) of the through hole, a base-material exposed surface (28) in which the base-material foil is exposed. The base-material exposed surface is disposed between a root (38) and a tip (40) of the terminal strip, and connects with the terminal strip.
