To provide a thin and small double-tuned circuit coil device.

The double-tuned circuit coil device is provided with a circuit board 1 where a primary-side coil L1 and a secondary-side coil L2 are arranged. A recess 1a is disposed in the circuit board 1. The circuit board 1 is provided with a printed coil 2 formed of a printed pattern consisting of a conductive material so that it surrounds an outer peripheral part of the recess 1a and a line coil 6 formed of a wire rod positioned in the recessed part 1a. Since the printed coil 2 or the line coil 6 is set to be the primary-side coil L1 and the other coil to the secondary-side coil L2, the line coil 6 becomes a state where it is positioned in the recess 1a, and the line coil 6 is prevented from being projected from a surface of the circuit board 1. Consequently, the thin coil device can be supplied.
