Abstract
There is provided an electric motor and a manufacturing method of the electric motor capable of joining a brush and a commutator without placing load on components. An electric motor is formed at a side of a brush holder 13 with a second notch unit 32, and a groove unit 36 is formed on a brush 12 so that it overlaps the second notch unit 32 in the position where the brush 12 stored in the brush holder 13 does not abut against a commutator 8. By doing so, when joining the brush 12 and the commutator 8, the brush 12 may be temporarily fixed with respect to the brush holder 13 by pushing in the brush 12 in the brush holder 13 and coinciding the second notch unit 32 and the groove unit 36, and fixing a jig and the like to the groove unit 36 in this state.
