The present invention relates to an electrode device for high-frequency thermal therapy in which a lesion site such as a cancer tissue of a body organ is heated and cauterized and necrotized by high-frequency, ultrasonic imaging, computed tomography (CT), magnetic resonance (MRI) guided high-frequency thermal therapy. When performing (RFA), the path before the insertion of the electrode is predicted by the position sensor of the handle part, and the path can be displayed so that the electrode needle after the insertion of the human body is accurately positioned in the lesion by the position sensor of the electrode needle part. The present invention relates to a human body insertion electrode position sensing device and method. The human body insertion electrode position sensing device according to the present invention includes a position signal generator for generating a position signal and an electrode side sensor for receiving the position signal and generating first position information inside the bar needle. And a handle that is coupled to the electrode needle and includes a handle-side position sensor that receives the position signal and generates second position information.
