Title:
ELECTRODE FOIL FOR ELECTROLYTIC CAPACITOR, ELECTROLYTIC CAPACITOR, AND METHODS FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2019/167773
Kind Code:
A1
Abstract:
This electrode foil for an electrolytic capacitor is provided with: an anode electrode body that has a base material part and porous parts; and a dielectric layer that covers the base material part. The anode electrode body is provided with a first main surface toward which the porous parts are open, a second main surface that is the rear surface of the first main surface, and an end surface that connects the first and second main surfaces. In a nearby region where the depth from the end surface is equal to or smaller than a prescribed distance, the film thickness TA of the dielectric layer formed along a porous part is larger than the film thickness T0 of the dielectric layer formed in a deep part, in the thickness direction, of a porous part at the central part of the first main surface.
