摘要：
A brushless motor includes a substantially flat attachment plate and a circuit board. The attachment plate includes a plurality of motor attachment portions and a base portion arranged to interconnect the motor attachment portions. The circuit board is arranged on an upper surface of the base portion and includes a first area to which electronic parts are attached. The upper surfaces of the motor attachment portions are arranged higher than the upper surface of the base portion. The height of the upper surface of the circuit board in the first area is substantially equal to or greater than the height of the upper surfaces of the motor attachment portions.
