PROBLEM TO BE SOLVED: To provide a coil which can be easily and finely regulated in inductance. SOLUTION: A coil is equipped with coil patterns 1 and 2 of a conductor printed on an insulating board 10, where points that are each on the coil patterns 1 and 2 and adjacent to each other are shorted with a jumper to determine the inductance of the coil.
