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.
