The method includes a step of pressing a sintered compact having sintered density that is equal to or greater than a relative density of 95%. In the pressing step, the sintered compact is pressed using an upper mold and lower mold having the shape of the shaft for the turbine rotor which has been split into two equal parts along the surface including the axis of rotation. In this case, after a first pressing operation is performed, the phase is shifted through no more than 120° to perform a second pressing operation, after which subsequent pressing operations are performed with the phases being sequentially shifted through no more than 120° till it is rotated by ≥360°.
