In order to prevent charging of a shaft of a rotor of a rotating electric machine with use of an inexpensive configuration, the rotor of the rotating electric machine includes a slip ring device (5) composed of: a pair of slip rings (51a, 51b); a pair of connection conductors (52a, 52b) electrically connecting the respective slip rings and a rotor coil (42); and an insulation molded body (53) holding the slip rings and the connection conductors. In the insulation molded body (53) of the slip ring device (5), the pair of slip rings and the pair of connection conductors are embedded and held such that the brush sliding surfaces of the slip rings and the lead-out-wire-connection end portions of the connection conductors are exposed in the outer circumferential direction, and at least one of the negative-side slip ring (51a) and the negative-side connection conductor (52a) embedded and held in the insulation molded body has a protrusion (55) extending toward the shaft (3) and electrically connected to the shaft (3).
