PROBLEM TO BE SOLVED: To efficiently form an electrodeposition coating of a magnet wire, while preventing the elution of copper ions and the like and the generation of oxygen gas. SOLUTION: An electrodeposition coating 8 is gradually thickly formed on a bare copper wire 7, while arranging a plurality of electrodeposition baths 2, 3, and 4 in which an electrode 5 is soaked in electrodeposition varnish 6, applying gradually high voltages to these electrodeposition baths 2, 3, and 4, and causing the bare copper wire (conductor) 7 to pass through the first low voltage electrodeposition bath 2 to the third high voltage electrodeposition bath 4 in sequence.
