A single-phase induction motor in which coils are wound around a plurality of teeth by a concentrated winding method is constructed such that an area of a smallest of all cross-sections of a core back element taken along planes which are parallel or substantially parallel to an axial direction is about 0.90 or more times an area of the smallest of all cross-sections of the teeth taken along planes which are parallel or substantially parallel to the axial direction, to prevent or minimize leakage of the magnetic flux.
