PURPOSE: A body heat generator using radio frequency is provided to enable a user to consecutively supply fixed electricity to skin regardless of the change of the load of skin. CONSTITUTION: A body heat generator using radio frequency comprises a radio frequency generator(50) which comprises two electrodes in a handpiece, generates body heat, and supplies radio frequency power, a matching circuit(60) which is placed in the front end of the electrode, an automatic phase control loop circuit which removes the phase difference of voltage and current, and an automatic gain control circuit which automatically controls the size of power which is supplied to the matching circuit.
