Abstract: Disclosed is a high frequency current output device enabling sequential output and continuous output of monopolar- and bipolar-type current. The device comprises: an electrode unit including one or more first electrodes and one or more second electrodes; a first high frequency power generation unit; a switching circuit; and a control unit for controlling a switching operation of the switching circuit so as to output, on the basis of the power generated from the first high frequency power generation unit, a monopolar-type current, in which the same polarity is applied to the first electrodes and the second electrodes, and/or a bipolar-type current, in which currents of different polarities are applied.
