Abstract
The invention provides a coil comprising a plurality of stacked coil elements connected together at conductor ends to form at least one series of spiral conductors, the coil being characterized in that each of the coil elements includes a sheet insulator, a first conductor in a planar spiral form and provided on one surface of the insulator and a second conductor in a planar spiral form and provided on the other surface of the insulator, the conductors on the respective surfaces of the insulator being wound spirally in directions opposite to each other when seen from above at the same side of the insulator.
