A radio frequency heating apparatus includes a printed circuit board on which power-supply noise filter circuit (20) that reduces power-supply noise generated by magnetron (15) and power-supply synchronization detecting circuit (21) that is connected across both terminals of power supply for detecting information on power-supply frequency are mounted. Power-supply synchronization detecting circuit (21) is used as a discharge path for charge accumulated at both ends of capacitor (3) configuring power-supply noise filter circuit (20). This achieves the radio frequency heating apparatus that eliminates the risk of electric shock, reduces power consumption, and reduces the number of components.
