There is provided an electric processing system which sequentially monitors a phase difference of intermittently output high-frequency powers in the case of performing feedback control with respect to a high-frequency power applied to bipolar type sealing forceps (2), reduces the high-frequency power and prolongs an application time at the time of occurrence of abnormal discharge (a spark) at distal ends, thereby terminating the abnormal discharge (extinguishing the spark) to carry out sealing processing.
