Title:
ELECTROLYTIC CAPACITOR, AND METHOD FOR MANUFACTURING ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2021/066091
Kind Code:
A1
Abstract:
An electrolytic capacitor 1 comprising: a cuboid-shaped resin molded body 9 comprising a layered body 30 that includes a capacitor element 20 including an anode 3 having a dielectric layer 5 on the surface thereof and a cathode 7 facing the anode 3, and a sealing resin 8 sealing the periphery of the layered body 30; a first external electrode 11 that is formed on a first end face 9a of the resin molded body 9 and is electrically connected to the anode 3 exposed from the first end face 9a; and a second external electrode 13 that is formed on a second end face 9b of the resin molded body 9 and is electrically connected to the cathode 7 exposed from the second end face 9b. The electrolytic capacitor 1 is characterized in that the first external electrode 11 and the second external electrode 13 have respectively: an Ag plating layer and a Cu plating layer (11a, 13a) formed respectively on the surface of the anode 3 exposed from the first end face 9a of the resin molded body 9 and on the surface of the cathode 7 exposed from the second end face 9b of the resin molded body 9; and resin electrode layers (11b, 13b) that are formed on the surface of the Ag plating layer and the Cu plating layer (11a, 13a) respectively and include a conductive component and a resin component.
