ABSTRACT:
A high-frequency power device including: an oscillator; a high-frequency power supplier; a reflection coefficient calculator; a discharge signal output unit; and a frequency controller, wherein the frequency controller: instructs the oscillator to oscillate the oscillation signal at a first oscillation frequency for the period of time while a discharge signal is not in a state showing that the discharge has been commenced or in a state where the discharge is regarded as having been commenced; then instructs the oscillator to change the first oscillation frequency to a second oscillation frequency immediately after the discharge signal changes into the states; and then controls the oscillation frequency so that the absolute value is made small.
