A rotor for use in a motor with a cooling function includes a main body and a plurality of cooling blades formed to be integrated with the main body. The main body includes attachment reinforcing openings and is formed by pressing soft magnetic powder. The cooling blades are formed through injection molding into the respective attachment reinforcing openings of the main body.
