Summary:PROBLEM TO BE SOLVED: To provide a brushless motor which has long term durability and suppresses disturbance voltage.SOLUTION: A brushless motor includes: a stator 10 formed by integrally molding a fixing member having a stator iron core 11 on which a stator winding 12 is wound by using an unsaturated polyester resin molding material 13; a rotor 14 in which a disk-shaped iron core holding a ferrite resin magnet 32 in the circumferential direction is disposed around a shaft 16 to oppose to the stator 10; a bearing 15 rotatably supporting the shaft 16; and conductive brackets 17, 19 for fixing the bearing 15. The brackets 17, 19 are electrically connected by a conducting member 22 covered with insulating resin within the stator 10.
