To provide a brushless motor having high resistance against vibration even when lead wires are not fixed using varnish or an adhesive. A brushless motor is provided with an insulator 4 mounted on a salient pole 3 of an armature coil 1 and an armature winding 5 wound around the insulator 4, and is configured so that the insulator 4 has a protrusion 4b on an end in the axial direction, the armature winding 5 is provided with two lead wires having wire starts 9a, 9c, 9e and wire ends 9b, 9d, 9f and a winding part formed between the two lead wires, and one of the lead wires is wound on the protrusion 4b up to an electric connection part 7a.
