A brushless motor is provided to realize high torque of the brushless motor by a simple configuration. A brushless motor comprises a rotor, a stator, a groove, a protrusion, a magnetic material and a magnetic connection member. The rotor has a surface where the N pole and the S pole are placed in turn. The stator includes a plurality of protrusions where a coil(31) is wound. The end tip of the protrusion faces against the surface of the rotor in a radial direction. The magnetic material is interposed between the groove and the surface while not contacting to either of them. The magnetic connection member(5) is arranged at a distance from the stator in an axial direction. The magnetic connection member connects the several magnetic materials magnetically.
