A yoke having a plurality of closely opposing magnetic pole pieces on its inner circumference is attached to a synthetic resin winding frame around which a winding is wound, and the outer circumferential surface of the yoke is in contact with the inner circumferential surface of the motor frame. A stepping motor comprising a stator fitted into the motor frame, and a resin filled between the stator and the motor frame and between the magnetic pole pieces that are inserted into each other. Arc-shaped notches for injecting the resin are formed along the circumference at two locations, and the diameter of the winding frame is set such that the outer circumference of the winding frame is closer to the inside of the motor frame than the bottom of the notch. 1. A stepping motor characterized in that the stepping motor is formed in a size that projects toward the circumferential surface side, and a lead wire connected to the winding is drawn out through between the outer circumferential surface of the winding frame and the inner circumferential surface of the motor frame.
