PURPOSE: A non-ablative radio-frequency treatment apparatus for a skin tissue using radio-frequency energy is provided to prevent an impact on a patient by moving an initial spark contact gap away from the skin of the patient. CONSTITUTION: A radio frequency unit(10) is connected to an elective surgery generator(8) by a standard cable(6). An end portion of an electroconductive shank of a non-ablative electrode(18) is stored to move in an axial direction. A handle or a handpiece(12) includes a front end portion and an operating button or a finger switch(14). An active electrode surface of the non-ablative electrode is formed into a round shape, a dome shape, or a cone shape. The handle is electrically insulated. The electrode is combined with elongated electroconductive shank by a screw. The electrode and the shank moves together in an axial direction in a central bore of the handler as like a single unit.
