Claim:
1. A stator for an electric rotating machine, the stator comprising: a hollow cylindrical stator core having a plurality of stator teeth and a plurality of slots, the stator teeth each extending radially inward and being spaced from one another in a circumferential direction of the stator core, each of the slots being formed between a corresponding circumferentially-facing pair of side surfaces of the stator teeth so as to open at a radially inner periphery of the stator core; and a stator coil comprised of a plurality of electric wires that are mounted on the stator core so as to be received in the slots of the stator core, wherein each of the stator teeth has a distal end portion and the distal end portion includes a slit, a base part and an oblique part, the slit is formed in a distal end surface of the stator tooth so as to continuously extend in an axial direction of the stator core over an entire axial length of the stator core, the base part and the oblique part are formed respectively on opposite circumferential sides of the slit over the entire axial length of the stator core, the base part extends radially inward so as to have a distal end surface that makes up an inner-diameter surface of the stator core, the oblique part is bent toward an adjacent one of the slots of the stator core so as to extend obliquely with respect to the base part, the stator core is comprised of a plurality of stator core segments that are arranged in the circumferential direction of the stator core so as to adjoin one another in the circumferential direction, wherein the oblique part has a constant width from a proximal end to a distal end of the oblique part, wherein the oblique part has a distal end surface that lies in the same cylindrical plane as the distal end surface of the base part, and wherein the stator coil is formed of a plurality of electric wires each having a substantially rectangular cross section.
