PURPOSE:To obtain coils excellent in mass-productivity, workability and heat- proof property, by mixing a mold unit with a fixing agent and filler for improving their heat resistance and workability on molding a strip conductor wound up in a coil shape. CONSTITUTION:Insulating coats 22, 23 are provided for a strip conductor 21 to form coil material 24, and by winding up the material on the periphery of a cylindrical core 25 via bonding agent, wound-up units 28 are produced. The wound-up units 28 are arranged in a specified quantity in metallic molds, and molding agent 30 is injected to be solidified. With the molding agent 30, fixing agent and filler for improving heat-proof and processing properties are arranged to be mixed. For the filler, talc, vitreous substance, metallic oxide and the like can be used. Finally, the mold unit is sliced in specified thickness to form coils. |
