Abstract

PURPOSE: To obtain an improved highly reliable high frequency coil capable of stable and precision frequency setting and facilitating adjustment operation by providing a support member having a threaded hole coaxial with an air-core coil and rotatably mounting an adjusting screw in the threaded hole.
CONSTITUTION: A support member 1 having a threaded hole 3 is provided coaxially with an air-core coil 5 and an adjusting screw 2 is rotatably mounted in the threaded hole 3. For example, by using a shielding case 1 for the support member for the adjusting screw 2, the air-core coil 5 is designed beforehand to be disposed in the vicinity of the shielding case 1. The air-core coil 5 is fixed to a circuit board 4 at a soldering part 6, and further, copper foil 7 on the rear surface of the circuit board 4 and the shielding case 1 are fixed to each other by soldering 8. Then, the threaded hole 3 is provided at the point where the extension of the central axis of the air-core coil 5 intersects the shielding case 1, and the electrically conductive adjusting screw 2 is inserted into the threaded hole 3 and the spacing between the front end of the screw and the nearest winding end of the air-core coil 5 is changed from the outside by rotating the adjusting screw 2 utilizing a screwdriver.
