Title:
ELECTROLYTIC CAPACITOR AND METHOD FOR MANUFACTURING ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2023/074375
Kind Code:
A1
Abstract:
The disclosed manufacturing method is for an electrolytic capacitor that includes a capacitor element. The manufacturing method includes, in this order: a step (i) for electrically connecting a positive-electrode lead terminal to a positive-electrode part, and electrically connecting a negative-electrode lead terminal to a negative-electrode part; and, a step (ii) for covering a portion of the positive-electrode lead terminal, a portion of the negative-electrode lead terminal, and the capacitor element with an exterior body containing a resin. The manufacturing method further includes, prior to step (ii), a plasma process step in which at least a portion of a metal surface of at least one lead terminal selected from the group consisting of the positive-electrode lead terminal and the negative-electrode lead terminal is subjected to a plasma process, thereby making the at least a portion a plasma process surface, whereby a method for manufacturing an electrolytic capacitor having high reliability is provided.
