However, in a high-frequency physical therapy apparatus using a high-frequency RF output signal and applying it to a human body, the output level is unstable and congestion may occur due to the use of a high-voltage current. Accordingly, a spark due to a high voltage occurs between the human body and the electrode There is a problem that the electrical stability in use is not ensured due to an image or an instantaneous electric shock from an improper high-frequency output generated from a high-frequency ceramics, etc., thereby causing a serious danger to the human body.
