PROBLEM TO BE SOLVED: To provide a brushless motor in which an electric error of a rotational angle that is detected by a resolver is made small. SOLUTION: The brushless motor 1 comprises: the resolver 13 that detects the rotational angle of a rotor 12 rotated by the magnetic field a stator 11 forms; the control device 3 that controls electric power supply to the stator 11 based on the detection signal of the resolver 13; and the sensor cable 5 that electrically connects an exciting coil 38 of the resolver 13, a SIN output coil 39, and a COS one 40 to the control device 3. The sensor cable 5 has lead wires 31-36 arrayed at prescribed circumferential positions around an enclosed shaft 30. The resolver 13 and the control device 3 are connected in such a way that the output signal of the SIN output coil 38 and that of the COS one 39 are transmitted by the lead wires at a position where impedance becomes almost equal.
