Title:

SOLID ELECTROLYTIC CAPACITOR AND METHOD FOR MANUFACTURING SAME

Document Type and Number:

WIPO Patent Application WO/2012/042950

Kind Code:

A1

Abstract:

Provide are: a solid electrolytic capacitor which has high volume/capacity ratio; and a method for manufacturing the solid electrolytic capacitor. Specifically provided is a solid electrolytic capacitor which is characterized in that: the solid electrolytic capacitor comprises a laminate that is obtained by laminating a plurality of valve-acting metal bases each of which has a first main surface and a second main surface facing each other and one or more lateral surfaces connecting the first main surface and the second main surface; each valve-acting metal base is provided with a dielectric oxide coating film that covers the first main surface, the second main surface and the lateral surfaces; a negative electrode layer is formed so as to cover at least a part of the dielectric coating film formed on the first main surface and the second main surface of each valve-acting metal base; the laminate has a through hole that penetrates therethrough in the lamination direction; the valve-acting metal bases are electrically connected with each other by a conductor that is provided inside the through hole; and the negative electrode layer and the conductor are insulated from each other by an insulator interposed therebetween.
