SOLID ELECTROLYTIC CAPACITOR AND METHOD FOR PRODUCING SOLID ELECTROLYTIC CAPACITOR

WIPO Patent Application WO/2024/048414

A1

This solid electrolytic capacitor is provided with a capacitor element, a sealed body, a first base electrode and a second base electrode. The capacitor element comprises a flat film-like main body that contains a valve-acting metal, a dielectric layer that is formed on a negative electrode formation region, and a solid electrolyte layer that is formed on the dielectric layer. In addition, the capacitor element has a positive electrode terminal region on which a solid electrolyte layer is not formed with respect to the main body, and a negative electrode formation region which comprises a solid electrolyte layer. The sealed body is obtained by stacking a plurality of capacitor elements and sealing the capacitor elements with an insulating resin; and the sealed body has a first end face in which end parts of positive electrode terminal regions are exposed in lines. The first base electrode is arranged on the first end face and contains a first element. The second base electrode covers the first base electrode and contains the first element and a second element. The second base electrode is an intermetallic compound of the first element and the second element.
