Abstract: PURPOSE:To minimize an in-phase current and to suppress the adverse influence of the in-phase current by providing an in-phase current monitor which detects and monitors the in-phase current and a means which regulates the reactance- component of a matching device so as to minimize the in-phase current. CONSTITUTION:Electrodes 15, 16 for treatment are set on a living body 17.

The in-phase current flows through the floating capacities between the cables 13, 14 and the ground and between the electrodes 15, 16 for treatment and the ground at this time. If the in-phase current is large, a disturbance in a heating pattern and a degradation in heating efficiency are resulted. In addition, troubles, such as electric shock by the high- frequency electrification, generation of noises to other apparatus, are generated. The in-phase current is, therefore, detected and monitored by the in-phase current sensor 10 and a current root is inputted to a control section if the in-phase current is large. The control section 9 regulates the in-phase current so as to minimize this current.
