PURPOSE: To provide a multilayer coil which is almost symmetric in shape horizontally or vertically and provide its winding method. CONSTITUTION: Prior to winding up a conductor 3 around a winding jig 1 comprising a magnetic core having at least two surfaces which opposed each other and a collar 5 installed on both sides of the magnetic core, the opposed surfaces are wound up in the form of a multilayer-solenoid winding while being fed at a 1/2 pitch of a wire diameter of the conductor. This construction makes it possible to provide a multilayer coil which is almost symmetric in the horizontal direction or the vertical direction. |
