To provide a DC motor in which the lifetime of a brush is prolonged.

The DC motor comprises an armature constituting a commutator by arranging a plurality of commutator segments radially on the outer circumference of a shaft while insulating from each other, a plurality of brushes formed by stacking high copper content materials 31, 32 and 33 and low copper amount materials 34 and 35 alternately in the radial direction from the inner diameter side and connecting the high copper content material 33 located on the outermost diameter side with a pigtail 30, and means for bringing each brush 3 into contact with the commutator segment with a specified pressure.
