PURPOSE:To obtain a resonance frequency at which optimum conductivity is easily obtained when a resonance type high frequency conductor is used by obtaining inductance variation and capacitance variation only by adding a simple adjusting mechanism. CONSTITUTION:An inductance conductor 12 is connected to one end part of one capacitor type electric conductors 11a between 11a and 11b which are positioned opposite each other in parallel. This inductance conductor 12 and one end part of the other electric conductor 11b are connected in common through an AC feeding part V by a slide metallic fitting 13. This slide metallic fitting 13 is slid on the inductance conductor 12 to increase or decrease the electric conductors 11a and 11b in inductance, thereby adjusting the resonance frequency omegao. Further, pressure plates 14a and 14b which press the electric conductors 11a and 11b in the opposite directions as shown by an arrow P are arranged long the conductors, and consequently the gap between the conductors 11a and 11b is varied by pressing to adjust the resonance frequency omegao by capacitor variation during the period.
