  • Publication number: 20170278595
    Abstract: This insulated wire includes an insulating coating formed on a surface of a conductive wire body, and a soldered portion for electric conduction. The soldered portion is formed by attaching dicarboxylic acid onto a surface of the insulating coating, and by performing solder plating in a state where the dicarboxylic acid is attached onto the surface of the insulating coating. In addition, this method for manufacturing an insulated wire includes a surface treatment step of attaching the dicarboxylic acid onto a surface of an insulating coating which becomes the soldered portion, and a soldering step of performing the solder plating by immersing the surface treated portion of the insulating coating in a heated solder melt.
