ABSTRACT:
A core material-including organic core board or inorganic sintered board1having a plurality of band-shaped conductor patterns2formed on its front and rear surfaces is sliced in a direction crossing the band-shaped conductor patterns2. End portions of the band-shaped conductor patterns2exposed on each of cut surfaces of the core board1are connected to one another by bridging conductor patterns formed on the cut surfaces. In this manner, at least one helical coil is provided. The inner diameter of the helical coil can be kept constant while coil pitch accuracy can be kept good.
