Abstract: An RF energy radiation device of this disclosure comprises: an oscillator; a power amplifier; a radiation element; a detector; and a controller. The oscillator generates an RF signal. The power amplifier amplifies the RF signal to output RF power. The radiation element radiates the RF power. The detector detects progressive wave power. The controller performs an RF power output control using a closed-loop control for setting an output set value of the RF power by a closed-loop and an open-loop control for setting the output set value of the RF power by an open-loop. In a burst operation alternately switching between a period of outputting the RF power and a period of stopping the RF power, the controller changes the RF power output control from the closed-loop control to the open-loop control when a specified condition for change is satisfied during the period of stopping the RF power.
