PROBLEM TO BE SOLVED: To provide a flywheel magnet rotor for an internal combustion engine capable of correcting imbalance of a mass even if a polar arc angle of an inductor magnetic pole formed on an outer periphery of a flywheel is large. SOLUTION: A mass imbalance correction weight 3 of non-magnetic material, correcting the imbalance of the total mass of the rotor generated by forming the inductor magnetic pole part 1d, is disposed at an inner-periphery section of a peripheral wall 1a of the flywheel 1, and the weight is fixed on the peripheral wall 1a of the flywheel 1.
