To provide a method for manufacturing a turbine wheel excellent in dimensional precision.

The method for manufacturing the turbine wheel includes a step for cutting a sintered compact 1' having a shape approximate to that of a desired final product, manufactured with a metal powder injection molding method and a step for pressing the sintered product. At the cutting step, a shaft coupling portion for inserting the distal end of a rotor shaft is formed by machining on the bottom surface of a central shaft portion, and at the pressing step, a plurality of correction pins 7 arranged radially relative to the fixed sintered compact 1', are slid toward the central shaft portion of the sintered compact while being synchronized simultaneously, and each correction pin 7 is press-inserted toward the control shaft portion, along each blade surface, such that each blade is held from the both sides.
