An armature includes a core having a plurality of teeth, which are radially formed with a rotation axis as the center, a plurality of coils where each coil is wound around each set of teeth containing at least two teeth. The plurality of coils have a plurality of inside coils placed on a rotation axis side of the teeth and a plurality of outside coils placed outside the inside coils. The plurality of inside coils are circularly arranged so that inside coils adjacent to each other are not wound around the same tooth. The plurality of outside coils are circularly arranged so that outside coils adjacent to each other are not wound around the same tooth. The outside coils are wound around a second set of combinations of teeth, which are different from a first set of combinations of teeth around which the inside coils are wound.

A DC motor includes a cylindrical yoke constituting a magnetic path, pole cores fixed to an inner periphery of the yoke so as to be arranged at even intervals along a circumferential direction of the yoke, and a field conductor that generates a magnetic field to magnetize the pole cores when supplied with a current. The field conductor includes inter-core conductors each of which extends in an axial direction of the yoke so as to be disposed between circumferentially adjacent pole cores. Each of the inter-core conductors is formed by integrating a first conductor part that generates a magnetic field to be applied to one of the circumferentially adjacent pole cores and a second conductor part that generates a magnetic field to be applied to the other of the circumferentially adjacent pole cores.
