PROBLEM TO BE SOLVED: To provide an electric motor with commutator in which a rotating strength (centrifugal strength) of a coil conductor in coil connections can be improved without increasing the manufacturing processes, and without increasing the costs. SOLUTION: In the solving means for solving the problem, a coil connection portion 34e is formed at a standing portion 34d of a conductor portion 34b so that a coil conductor 32a can be incorporated from axial direction. By this formation, at the outer perimeter side of the coil connection portion 34e, an anti-slip-off portion 34f is formed integral with the conductor portion 34b in order to prevent slipping off toward centrifugal direction from the coil connection portion 34e of the coil conductor 32a. Thereby, with the solving means, a rotational strength (centrifugal strength) of the coil conductor 32a in the coil connection portion 34e can be improved without adding new materials as the anti-slip-off portion 34f and without increasing the work processes involved in the anti-slip-off portion 34f.
