A brushless motor comprises a rotor and a stator comprising a plurality of core plates laminated on one another. The core plates include a plurality of teeth portions. The plurality of core plates includes a first core plate and a second core plate, a combination of magnetic resistances of the teeth portions of the first core plate being adjusted at a first condition, and a combination of magnetic resistances of the teeth portions of the second core plate being adjusted at a second condition. Magnetic resistances of magnetic paths formed by the plurality of laminated teeth portions are adjusted to be same by adjusting a ratio of a number of the first core plates to a number of the second core plates.
