Abstract
The electric rotating machine includes a rotor, a stator having a stator core and a stator winding wound on the stator core, and a cooling liquid feeding function of applying cooling liquid to the coil end of the stator winding. The stator winding constituted by coils wound along the circumferential direction includes crossover portions each of which electrically connects the ends of two of the coils through which currents in the same phase flow, respectively. The crossover portions are arranged so as to overlap one another only partially in the circumferential direction. The cooling liquid feeding function applies the cooling liquid to at least one of the crossover portions.
