Disclosed herein is a method for adjusting the tuning frequency of a tuning circuit, which is implemented as a parallel circuit of a coil and series circuits Ai each including a capacitor Ci and a switch device Qi (i=one to n, where n denotes an integer at least equal to two), by varying the tuning frequency through control to turn on and off the switch devices Qi in accordance with control data bi, the method for adjusting the tuning frequency of a tuning circuit including the steps of: finding control data bi for a desired tuning frequency from control data bi for a tuning frequency equal to a first frequency and control data bi for a tuning frequency equal to a second frequency; and applying the control data bi found for the desired tuning frequency to the switch devices Qi.
