To achieve a DC motor capable of performing good rectification without causing a hindrance to commutator rotation, in a configuration using a power feeding brush rolled by contact with a commutator.

A DC motor has: a commutator which rotates; and a power feeding brush which rolls by contacting with the commutator in a rotation state. The commutator has a plurality of segments aligned in the rotation direction, and a plurality of slits formed between the segments. A formation direction of each slit is inclined to an axial direction of the center axis at rolling of the power feeding brush.
