ELECTRIC WIRE, AND MANUFACTURING METHOD FOR ELECTRIC WIRE

PROBLEM TO BE SOLVED: To provide an electric wire and a manufacturing method for the electric wire, achieving space-saving and cost reduction without damaging an external coating appearance. SOLUTION: A surface side of an extrusion coating 7 prior to becoming an insulator 3 is bridged with electron beam irradiation with low energy in a surface side bridging process, and a low-energy electron beam irradiated bridge section 4 with dozens of microns thickness is formed in this process. An inner side rather than the surface side of the extrusion coating 7 prior to becoming the insulator 3 is heated by induction heating or microwave heating in an inner side bridging process, and is thermally bridged. An induction heating bridge section 5 (or microwave heating bridge section 6) is formed on an inner side of the low-energy electron beam irradiated bridge section 4 by the process. The insulator 3 having the low-energy electron beam irradiated bridge section 4 and the induction heating bridge section 5 is formed on a conductor 2 through these processes.
