VEHICLE DRIVE UNIT

In a vehicle drive unit, a motor and an inverter are disposed adjacent in an axial direction of the motor. A smoothing capacitor and each power module are connected by a busbar. Each power module has a flat shape having a wide width, and has a first cooling surface facing the motor. The first cooling surface of each power module is placed on a placement surface orthogonal to the axial direction. The plate-shaped busbar has a second cooling surface facing the motor. The busbar is connected to the smoothing capacitor and each power module, and is formed with a wide width so as to extend along a direction in which each power module is disposed side by side. The second cooling surface is placed on the placement surface. A cooling portion facing the first and second cooling surfaces is provided closer to the motor than the placement surface.
