PROBLEM TO BE SOLVED: To provide a system for correcting rotation balance which performs corrective working of a correcting object part with improved accuracy. SOLUTION: The system includes a magnetometric sensor which is installed opposite to the shaft end face of a rotating shaft magnetized to be bisected into an N pole and an S pole, an acceleration sensor which is installed at a rotatory support supporting a high-speed rotation body so that it rotates at a high speed, a balance operation processing part which calculates the amount of correction and the angle of correction of the correcting object part, based on output signals of the magnetometric sensor and the acceleration sensor, and also calculates an offset amount contained in the output signal of the magnetometric sensor, a balance correction working part which performs the corrective working of the correcting object part, based on the amount of correction, after positioning of the angle of rotation of the rotating shaft is performed based on the angle of correction, an addition part which adds the offset amount to the output signal of the magnetometric sensor, and a reference signal generating part which generates an origin reference signal necessary for a return to the origin of the rotating shaft before positioning by the balance correction working part, from the output signal of the magnetometric sensor after the addition of the offset amount.
