A brushless motor is provided to facilitate an assembling process of the motor by directly coupling a bearing with a core without using the base holder. A brushless motor(100) includes a magnet(110), a rotational shaft(120), a core(130), a coil(140), and a first bearing(152). The magnet is rotated around the rotational shaft. The core is insert-molded by using a predetermined synthetic resin. The core contains the rotational shaft therein. The coil generates a rotating magnetic field in the core by using a three-phase current. The coil rotates the rotational shaft. The first bearing rotatably supports the rotational shaft. The first bearing is directly integrated with and inserted into the core. The first bearing is insert-molded with the core as one entity.
