A frequency matching section (24; 24, 30, 31) is configured to match the resonant frequency of a resonant system (20) and the output frequency of a high frequency power source (11) with each other when the load (16) fluctuates. An impedance matching section (17, 24) is configured to match the impedance from input terminals (12a, 12b) of the primary coil (12) to the load (16) at the resonant frequency and the impedance from the high frequency power source (11) to the input terminals (12a, 12b) of the primary coil (12) with each other.",
