A low-profile stepping motor has a stator assembly structured such that first and second coil units are disposed flush with each other horizontally and are sandwiched between upper and lower stator yoke pieces each comprising first and second stator yokes which are punched out integrally with each other, are shaped symmetrically, and which each have a plurality of pole teeth along its semi-circular inner circumference. The upper and lower stator yoke pieces are fixedly put together by means of two studs lodged fittingly inside respective bobbins of the first and second coil units such that the studs have their both ends tightly engaging with holes formed in the upper and lower stator yoke pieces, whereby the coil units are surely held between the upper and lower stator yoke pieces.
