Abstract
A method for manufacturing a stator of a stepping motor comprises the steps of carrying out a half-pierce and push-back process to a frame plate to make an area in which comb teeth are to be formed and an area to be blanked out readily separable, carrying out a blanking process to separate the blanked out area from the comb teeth, and bending the comb teeth to a predetermined angle and collapsing the comb teeth to make the thicknesses of the comb teeth uniform. The comb teeth are then bent at right angles to an outer periphery of the frame plate.
