<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of an insulation wire, in which an organic solvent surely penetrates into gaps between fine resin particles to melt the fine resin particles so as to eliminate the gaps, thereby reducing pin holes and achieving excellent insulation properties. <P>SOLUTION: A manufacturing method of an insulation wire comprises steps of: forming a sparse electrodeposition coat by causing a conductor 1 to travel from bottom to top in an electrodeposition bath 10 to cause a myriad of fine resin particles 11 to adhere to the conductor 1; forming a dense electrodeposition coat by bringing an organic solvent mixture K, in which vapor J of an organic solvent is mixed with mist M of an organic solvent sprayed from an injection nozzle 21, into contact with the sparse electrodeposition coat to melt the fine resin particles 11 of the sparse electrodeposition coat; and forming an insulation layer on the conductor 1 so as to cover the conductor 1 by burning the dense electrodeposition coat onto the conductor 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
