There is a problem in that there is a risk of causing an accident such as a burn if a high-frequency signal is excessively energized to the skin. A high frequency device includes an oscillation circuit and an amplification circuit that generate a high frequency signal, and a head that holds terminals 41x and 41y for energizing the skin with the high frequency signal generated by the oscillation circuit and the amplification circuit. In the treatment apparatus, an energization site changing means for changing the energization site of the skin S between one of the terminals 41x and 41y during the energization of the high frequency signal is provided.
