A rotating electric machine having high efficiency and high reliability without causing an increase in size and cost is realized. Each of the rectangular wire segment coils has a first region portion and a second region portion connected to the first region portion and formed in the circumferential direction including a bent portion in the circumferential direction of the stator core 10, and a pair of the rectangular wire segment coils adjacent to each other at the coil ends of the plurality of rectangular wire segment coils has a conductive portion to which the first region portion of one of the rectangular wire segment coils and the second region portion of the other of the rectangular wire segment coils are connected. The second region portion has a conductive portion cross-section disposed on the same plane as the end portion cross-section of the first region portion, and the conductive portion cross-section is a cross-section in a direction different from a direction of the coil vertical cross-section of the second region portion. Each of the plurality of layers includes a first layer in which the first region portion appears at an axial end portion and a second layer in which the second region portion appears at an axial end portion when the coil end is viewed in an axial direction of the rotating electric machine.
