A low-profile stepping motor comprises: a first stator unit including first upper and lower stator yokes each having a plurality of pole teeth which are formed along its semicircular inner circumference, and a first coil unit fixedly sandwiched between the first upper and lower stator yokes; a second stator unit including second upper and lower stator yokes formed as one piece integrally with the first upper and lower stator yokes, respectively, and each having a plurality of pole teeth which are formed along its semicircular inner circumference, and a second coil unit fixedly sandwiched between the second upper and lower stator yokes; a rotor assembly rotatably disposed in a circular open space defined by the pole teeth of the first and second stator units; and a spacer block disposed between the upper and lower stator yokes and adapted to surround the first and second coil units and the pole teeth.
