Abstract
The manufacturing method of a rotor includes: a step of preparing a plate that is composed of an austenitic material and that has a projected portion and a part with a width in a rotational axis direction smaller than a width of the projected portion in the rotational axis direction; and a step of forming a welded portion across the projected portion of the plate and a rotation transmitting member by emitting an energy beam on at least a part of the projected portion to melt at least a part of the projected portion.
