Abstract
An imbalance correction position of a turbine wheel head is irradiated with a laser beam so that an outer peripheral portion of the turbine wheel head is left, and a groove provided by the laser irradiation is provided so that a depth of the groove is shallower toward a side closer to an outer periphery of the turbine wheel head. This makes it possible to secure a strength of a base part of an outer peripheral portion (an outer wall) of the groove, thereby making it possible to restrain deformation of the outer peripheral portion of the groove due to a centrifugal force acting by rotation of the turbine wheel head.
