ABSTRACT:
A stator of a rotating electric machine is obtained, in which material usage in a conductor connection section of a stator coil end and weight of the conductor connection section are reduced, so that vibration suppression is improved, in addition, thermal resistance between a loss occurrence portion and a cooled portion becomes smaller so that temperature rise is suppressed. It is configured that a stator has first and second wire groups disposed at an inner diameter side of a slot, third and fourth wire groups disposed at an outer diameter side of the slot, and a connection conductor for connecting the respective, two wire groups to each other in a radial direction, wherein the stator further has a connection conductor which has one end being interposed between projected ends of the first and second wire groups, and connected to the respective projected ends, and has the other end being interposed between projected ends of the third and fourth wire groups, and connected to the respective projected ends, in addition, has axial through-holes, which communicate with flow paths of coolant flow members provided between the wire groups, in the one end and the other end respectively.
