To simplify wiring and downsize the entire device at the same time. The present invention relates to a drive device for a hybrid vehicle. The drive device includes a first inverter 30 that controls a rotary electric machine and a second inverter 40 that controls a pump motor. The first inverter 30 and the second inverter 40 are connected to a common DC power source. The first inverter 30 and the second inverter 40 are disposed in a case 2. A first wiring member 60 that extends from the DC power source is branched in the case 2 to be connected to each of the first inverter 30 and the second inverter 40.
