Electric wire equipped with terminal fitting and method of manufacturing the same

A method of manufacturing an electric wire equipped with a terminal fitting, the electric wire including:

• an electric wire including a metallic core wire coated with a coating;
• and a terminal fitting made of a metal different from that of the metallic core wire and including an electric wire connection portion, the method sequentially comprising:
• removing an end of the coating of the electric wire to expose a part of the metallic core wire;
• soldering an area from the exposed portion of the metallic core wire in the electric wire to a part of the coating adjacent to the metallic core wire with a solder containing a metal having an ionization tendency close to that of the terminal fitting as a main component, thereby forming a solder seal;
• forming a seal connection portion connecting the solder seal and the coating adjacent to the end of the metallic core wire that is exposed, with the solder seal and the coating sealed off from each other;
• and
• crimping the electric wire connection portion of the terminal fitting to the solder seal.
