To provide a brush capable of securely preventing internal conduction even when an insulating layer is reduced or disappeared in thickness due to an adhesive used in a division brush, and a motor including the same.
A brush includes a plurality of body conductive pieces 11A, and at least one insulating layer 11B. The insulating layer 11B is laminated so as to be held between the plurality of body conductive pieces 11A. The insulating layer 11B is formed of a liquid adhesive 11c mixed with dielectric powder 11d. The plurality of body conductive pieces 11A are bonded by the insulating layer 11B. The insulating layer 11B is laminated so as to be arranged along a slit formed between commutator pieces 4a adjacent to each other on a slidable contact surface T in slidable contact with a commutator 4 when a brush 11 is installed opposite to the commutator 4.
