PURPOSE:To permit the reduction of man-hours and increase of mass-producing quantity by a method wherein a brushless motor is thinned and the automation of the assembling of a coil unit is permitted without changing the characteristics or the diameter of the motor. CONSTITUTION:A plurality of flat coils 6, arrayed so as to surround the axial center of the rotation of a rotor, are formed on the surface of a thin sheet type insulating substrate 8 or a sheet type insulating substrate 8 through etching or printing while the insulating substrate 8 is attached to the surface of a base plate 1. |
