PURPOSE:To reduce the generation of capacitance between windings at high frequency by setting up a conductive member, one side thereof is opened between the coil windings and a residual one side thereof is grounded, in a bifilar winding shape when a coil is manufactured by winding a conductor on a ferromagnetic-material magnetic core plural times. CONSTITUTION:The coil for a high frequency circuit is manufactured by winding the conductor 22 on an annular core 21 consisting of a ferromagnetic material several times as follows. That is, the conductive member 23, one side thereof is grounded and the residual one side thereof is brought to an open state, is wound among the conductor 22 while being wound in a bifilar shape. Accordingly, the generation of capacitance among the windings is reduced, and the coil of excellent electric characteristics is obtained. |
