There is provided a compressor motor in which a teeth member and a yoke member are bonded while inhibiting deformation of bridge portions and which is capable of decreasing drop of torque due to a leakage magnetic flux. A stator is constituted of a teeth memberin which inner end portions of adjacent teethare continuous in a bridge portion and on which wires are wounded, and a yoke memberbonded to an outer side of the teeth member to form a magnetic path, the yoke member includes press-fitting concave regionswhich are opened inwardly and into which outer end portions of the teeth are press-fitted, and inner side surfacesA of the press-fitting concave regions which face each other possess projecting shapes, respectively, and both side surfacesB of each of the outer end portions of the teeth are formed in a recessed shape which matches the shape of the inner side surfaces of the press-fitting concave regions.
