Title:
METHOD FOR MANUFACTURING ELECTROLYTIC CAPACITOR
Document Type and Number:
Japanese Patent JP2022115735
Kind Code:
A
Abstract:
To provide a method for manufacturing an electrolytic capacitor having small variation of characteristics.SOLUTION: A manufacturing method to be disclosed includes a process (iii) for oxidizing at least a portion of the surface of an anode body to form a dielectric layer by applying a direct current voltage between a first electrode 210 and a second electrode 220 in a state in which the anode body is immersed in a chemical conversion liquid 202. In the process (iii), at least one selected between a distance between first and second anode bodies 113a and 113b and the second electrode 220, and the area of the second electrode 220 facing the first and second anode bodies 113a and 113b is made different between the first anode body 113a and the second anode boy 113b so as to reduce difference between conversion current flowing to the first anode body 113a existing at an end and conversion current flowing to the second anode body 113b existing on an inner side of the first anode body 113a.SELECTED DRAWING: Figure 1
