Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method for attaining the most suitable dimensional accuracy, related to a rotor of a centrifugal compressor. SOLUTION: In the manufacturing method for the rotor 10, a tool 20 of a numerical control machine having a plurality of controlled shafts is used, an outside section of a radial cavity is formed by machining until the outside section of the radial cavity 12 corresponding to an outer diameter reaches the middle with respect to the radial width of a round ring of an integrated structural disk by starting from the outer diameter of the integrated structural disk, an inside section of the radial cavity 12 is formed by machining until the inside section of the radial cavity corresponding to an inner diameter reaches the middle with respect to the radial width of a round ring of the integrated structural disk by starting from the inner diameter of the disk, and the radial cavity 12 is completed by substantially advancing the tool in the radial direction to the middle with respect to the radial width of the round ring of the integrated structural disk until the tool reaches the other side from one of an outer side or an inside section.
