A manufacturing method for a toothed member includes a thickened tooth shaping process in which a toothed shape is formed on a side wall portion while making a thickness of the side wall portion larger than a thickness of a bottom surface portion by relatively moving the compression die with respect to the restraint die and the pressure receiving member in the axial direction from the side of the opening end of the cup-shaped raw material toward the bottom surface portion. The manufacturing method being such that the thickened tooth shaping process includes applying a load against the restraint die such that the restraint die restrains the first surface and the second surface.
