Abstract
Provided is a rotating electric machine capable of improving heat dissipation from each of busbars to achieve a higher output. The rotating electric machine includes: a stator core (8); a frame (3); coil portions; a plurality of busbars (18, 19, 20) arranged on one end surface side of the stator core (8), which are to be electrically connected to the coil portions to distribute electric power to the coil portions; a holder (17); and a plate (24) having one end portion facing at least one of the plurality of busbars (18, 19, 20) and another end portion exposed externally from the holder (17) to be held in contact with an outer circumferential surface of a jacket (4). The plate (24) guides heat of the plurality of busbars (18, 19, 20) from the one end portion to the another end portion.
