PURPOSE:To improve the yield by slicing a molded unit by a wire saw or band with prescribed abrasive when manufacturing a coil product by forming a platelike conductor in a coil shape of its section, then molding it to form the molded unit, and sliding the unit. CONSTITUTION:A copper foil 2 is formed with an epoxy adhesive insulating layer 1 on the surface is densely wound in a coil shape of its section in a heated state to manufacture a coil part 3. Then, a molded unit 5 in which four coil parts 3 are annularly disposed is manufactured. The unit 5 is sliced by a wire saw or band with abrasive having 10-30mum of particle size to manufacture a coil product. |
