Zusammenfassung:PROBLEM TO BE SOLVED: To provide a frequency adjusting method which can easily adjust the frequency of an identification label to a planned frequency, and to provide an identification level suitable thereto. SOLUTION: By the frequency adjusting method for an identification label made of a composite film which has a frequency lower than the planned frequency, the frequency of the identification label supplied successively from a feeder A is measured by an impedance measuring instrument B and compared with the planned frequency and according to the frequency difference detected by the comparison, a correcting means C decreases the area of a capacitor part of an oscillation circuit.
