PURPOSE:To obtain a print coil which is fixed with conductors on its both surfaces by fixing a spiral or zigzag shaped conductor with an insulating material on one surface of a dielectric substrate and also by fixing similarly a conductor on the other surface of the substrate. CONSTITUTION:A spiral conductor 7 is fixed with an insulating material 6 on one surface of a dielectric substrate 5 and a conductor 8 is fixed with an insulating material 6 on the other surface of the substrate 5. A through-hole 9 is penetrated in the dielectric substrate 5 and the end 7a of the conductor 7 and the end 8a of the conductor 8 are electrically connected. As a result, required inductance value can be obtained between the end 7b of the conductor 7 and the end 8b of the conductor 8. The floating capacity Cp1 between each fringe of the conductor 7 and the conductor 8 and the floating capacity Cp2 between the conductor 7 and the conductor 8 are also small.
