Title:
SOLID ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2024/048412
Kind Code:
A1
Abstract:
A solid electrolytic capacitor according to the present invention comprises a capacitor element, a sealing member, an external electrode, and a spacer. The capacitor element includes a flat film-like main body which contains a valve action metal, a dielectric layer which is formed on a negative electrode formation region, and a solid electrolyte layer which is formed on the dielectric layer. The capacitor element has a positive terminal region, in which the solid electrolyte layer is not formed with respect to the main body, and the negative electrode formation region, in which the solid electrolyte layer is formed with respect to the main body. The sealing member forms a sealed body by sealing the capacitor element. The external electrode is embedded in the sealing member so that a portion thereof is exposed from the outer surface of the sealed body. The spacer is formed in a region in which the sealing member is in contact with the external electrode. The spacer melts in response to a rise in temperature.
