Abstract
Obtain a rotary electric machine by which a share of coil slots for a stator winding in slots, which are formed in a stator core, can be increased, and heat generation at a central portion of a stator can be decreased. The stator winding is composed of coil slots, which are inserted to the slots, and coil ends extended toward the outside in the axis direction of the stator core; and the coil conductors of the coil slots are configured in such a way that cross-sectional areas at central portions in the axis direction are wider cross-sectional areas at both end portions, and the cross-sectional areas of the coil conductors are reduced along the coil slots from the central portions to the both end portions.
