DISCLOSED IS A HIGH-FREQUENCY TREATMENT DEVICE PROVIDED WITH: AN OSCILLATOR CIRCUIT (20) AND AN AMPLIFICATION CIRCUIT (30) THAT GENERATE A HIGH-FREQUENCY SIGNAL； AND A HEAD THAT HOLDS TERMINALS (41X AND 41Y) THAT RUN THE HIGH-FREQUENCY SIGNAL GENERATED BY THE OSCILLATOR CIRCUIT AND THE AMPLIFICATION CIRCUIT THROUGH SKIN. TO ADDRESS THE PROBLEM THAT RUNNING AN EXCESSIVELY STRONG HIGH-FREQUENCY SIGNAL THROUGH SKIN CARRIES THE DANGER OF CAUSING BURNS OR OTHER ACCIDENTS, THE DISCLOSED HIGH-FREQUENCY TREATMENT DEVICE IS PROVIDED WITH A CURRENT-CARRYING REGION CHANGE MEANS THAT CHANGES THE REGION OF THE SKIN TO WHICH CURRENT IS APPLIED, FROM ONE OF THE TERMINALS TO THE OTHER, WHILE THE HIGH-FREQUENCY SIGNAL IS BEING APPLIED.
