Abstract: Provided is a brushless motor having high vibration resistance without fixing a lead wire with varnish or an adhesive. A brushless motor is configured to include: an insulator attached to a salient magnetic pole portion of an armature core; and an armature winding wound around the insulator, in which the insulator has a protrusion at an end portion in an axial direction, the armature winding includes two lead wires of a winding start lead wire and a winding end lead wire and a winding portion formed between the two lead wires, and one of the lead wires is wound around the protrusion before reaching an electrical connection portion.
