Disclosed is a high-frequency treatment device provided with: an oscillator circuit and an amplification circuit 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.
