A treatment device using a high frequency according to the present invention includes: a plurality of electrodes which transfers high frequency energy to the skin a plurality of pads each of which is provided on one surface thereof with at least one of the electrodes and a plurality of elastic members which independently and elastically support the other surfaces of the plurality of pads, respectively, so that plurality of electrodes can be three-dimensionally and closely attached to the curved surface of the skin. Accordingly, even when treating a body region having many curves, the attachment of the electrodes is efficiently maintained. In addition, although a hand piece moves in a state in which the plurality of pads are attached to skin, the plurality of pads can be maintained in the skin attached state while actively coping with the curves.
