Zusammenfassung:	In the present invention, a shaped article W is produced, the shaped article including: a plurality of blades provided around a shaft, with an interval disposed therebetween in the circumferential direction; and curved surface-shaped recesses present in between the blades. This method for producing a shaped article comprises: a shaping step, in which welding beads where filler material has been melted and solidified at the peripheral surface are layered on a base material having a circular cross-section of a greater diameter than the bottom circle that passes through the lowest part of the recess, thus forming a shaped section that will become a blade; and a cutting step in which part of the surface of the shaped section and the peripheral surface of the base material is cut to form a blade, and the recesses between the blades are also formed.
