Abstract: A balance adjustment method for a rotor includes an imbalance acquisition step of acquiring imbalance position and amount of the rotor after a first balance correction step of correcting balance of the rotor by cutting a compressor wheel side, an excision target section determination step of determining, based on the imbalance position and amount of the rotor, an excision target range including an imbalance correction position of the turbine wheel and a removal amount in the excision target range, and a second balance correction step of correcting the balance of the rotor by repeatedly irradiating the excision target range determined in the excision target section determination step with laser light from a laser marker device to remove by the removal amount from the turbine wheel.
