In a high frequency power supply device, an inverter section is connected to the transistor switching control section, and the transistor switching control section is controlled by the high frequency generation stop control signal to control the generation stop of the transistor switching control signal supplied to the inverter section. is inserted in series between the normally closed contact of the above relay connected between the output terminals of the control signal generator and the transistor, and delays the change point of the high frequency generation stop control signal from stop to generation by T 1 second. An ON delay circuit, and an OFF delay circuit inserted in series between the control signal generation section and the transistor switching control section to delay the change point from generation to stop of the high frequency generation stop control signal by T 2 seconds. A high frequency power supply device characterized by:
