PROBLEM TO BE SOLVED: To efficiently remove electric noises generated due to friction between a brush and a commutator with a simple configuration in a motor with a brush. SOLUTION: The motor 10 with the brush is provided with the brush 26 having an end contacting the commutator 20, and a brush holder 28 consisting of an insulating material and housing the brush 26 so that the brush can move for the commutator 20. The motor 10 is provided with a positive electrode 36 provided on the internal surface of the brush holder 28 and having conductivity, and a negative electrode 34 provided on the external surface of the brush holder 28 and having conductivity. In this motor, the brush holder 28 provided between the positive electrode 36 and the negative electrode 34 is used as a capacitor for removing electric noises to be generated between the brush 26 and the commutator 20.
