To provide a rotary electric machine driving unit which allows size reduction.SOLUTION: A rotary electric machine driving unit 10 comprises: a first rotary electric machine 12; a second rotary electric machine 13; a power control unit 200 which has a first power conversion circuit part 31 and a second power conversion circuit part 32; a first connection member 1b which electrically connects the first rotary electric machine 12 to the first power conversion circuit part 31; and a second connection member 1c which electrically connects the second rotary electric machine 13 to the second power conversion circuit part 32. At least the first rotary electric machine 12 is housed in a rotary electric machine housing part 61 of a rotary electric machine housing 60. When viewing from the rotational axis direction, the rotary electric machine housing part 61 has, between the first connection member 1b and the second connection member 1c, a bulging part 64 which bulges outward, and the first rotary electric machine 12 is housed in the rotary electric machine housing 60 so that a portion thereof is located in the bulging part 64.SELECTED DRAWING: Figure 6
