SOLID-STATE ELECTROLYTIC CAPACITOR MANUFACTURING METHOD AND SOLID-STATE ELECTROLYTIC CAPACITOR

摘要

Provided is a method of manufacturing a solid-state electrolytic capacitor with a large static capacity per unit of area. Coat a region of a portion of the obverse face of a dielectric coated valve-action metallic sheet (1), comprising a valve-action metallic substrate (11) and a dielectric film (13) which is coated on the obverse face thereof, with a wax material (17a, 17b). Stack a plurality of the dielectric coated valve-action metallic sheets (1) such that gaps are therebetween and the positions of the regions which are coated with the respective wax material (17a, 17b) are aligned, obtaining a layered body of the dielectric coated valve-action metallic sheets (1). In the stacked plurality of dielectric coated valve-action metallic sheets (1), adjacent valve-action metallic substrates (11) are bonded using the wax material (17a, 17b), thus obtaining a bonded layered body (3). Form a solid-state electrolytic layer (5) as a contiguous layer so as to fill the gaps between the dielectric coated valve-action metallic sheets (1) in the layered body and cover the exterior obverse faces of the layered body.
