PROBLEM TO BE SOLVED: To provide the brushless electric motor produced at a cost as low as possible. SOLUTION: The brushless electric motor 10 is provided with a stator 12 having a magnetic pole element 14, a magnetic pole 30 arranged to relatively freely rotate with the stator 12 to be molded by solidifying powder having magnetism, and a rotor 20 including a magnetism holder 26 carrying the magnetic pole 30. For producing the brushless electric motor 10 at a cost as low as possible, the magnetic pole 30 is made so as to be molded as at least one molded magnetic unit 30 directly molded on an external peripheral surface of the magnetism holder 26 in the magnetism holder side of the magnetic pole 30.
