| description | PROBLEM TO BE SOLVED: To provide a high-frequency power source device for dielectric heating capable of continuing welding operations, in case breakdown or corona discharge generated during a welding operation temporarily occurs without affecting quality of a heated body. SOLUTION: The high-frequency output portion 10 generates and outputs high frequency having a predetermined frequency. A high-frequency impression portion 20 impresses the high frequency outputted from the high-frequency output portion 10 to a pair of electrodes 61, 62 of a processing portion 60. The processing portion 60 uses the high frequency impressed to the pair of electrodes 61, 62 by the high high-frequency impression portion 20 to process a heated body 63. A breakdown detection portion 30 detects a breakdown phenomenon generated at the processing portion 60. A discharge detection portion 40 detects a discharge phenomenon generated at the processing portion 60. Based on the detected results at the breakdown detection portion 30 and the discharge detection portion 40, an output control portion 50 controls the high-frequency output from the high-frequency output portion 10 through a temporary stoppage or a complete shut down.
