PURPOSE:To offer a coil not lowering heat resistance and insulating performance even at a high temperature. CONSTITUTION:A heat-resisting electric insulating conductor is composed by containing a conductive material 1, a mixed lemination 2 consisting of a conductive material, and an inorganic hard insulating material formed by thermal spray on the surface of aforesaid conductive material 1 and an insulating film 3 consisting of an inorganic hard insulating material formed on aforesaid mixed lamination 2 by thermal spray. Further, intergrain voids and cracks on the surface of the insulating film 3 are filled with an inorganic hard insulating material. The heat-resisting electric insulating conductor is composed by containing the conductive material 1, the mixed lamination 2 consisting of the conductive material and the inorganic hard insulating material formed on the surface of the conductive material by thermal spray and the insulating film 3 consisting of the in-organic hard insulating material formed by thermal spray on aforesaid mixed lamination 2 while the voids and cracks on the surface of the coil formed of the heat-resisting insulating conductor, are filled with the inorganic curing insulating material. The heat-resisting conductor having generation of rether crack nor separation even at the high temperature and having no damage of electric insulation can be offered while suppressing lowering of heat resistance and insulating performance of the coil at a high temperature. |
