SOLID ELECTROLYTIC CAPACITOR, ELECTRONIC COMPONENT MODULE, METHOD FOR PRODUCING SOLID ELECTROLYTIC CAPACITOR AND METHOD FOR PRODUCING ELECTRONIC COMPONENT MODULE

摘要

A solid electrolytic capacitor that includes a capacitor element; an exterior resin; an anode lead terminal; and a cathode lead terminal. The anode lead terminal has a Cu base material, and an Au-plating layer formed thereon, and includes an Au region where the Au-plating layer as a surface layer is formed, and a Cu region where the Au-plating layer is not formed. The cathode lead terminal includes a base material, and an Au-plating layer as a surface layer of the cathode lead terminal, which is formed on the base material, and an anode section of the capacitor element is connected to the Cu region of the anode lead terminal.
