A small-sized stepping motor provided with can-type stator yokes and one flat-type stator yoke, all of which are injection molded of a composite powder (i.e., a mixture of a metal powder of a soft magnetic material, a powder of a thermoplastic synthetic resin). The injection molded stator yokes have a considerably large specific electrical resistance, and the stepping motor is free from various disadvantages resulting from a small specific electric resistance.
