Disclosed is a vehicular drive device comprising a rotating electrical machine, a differential transmission device, a power transmission device, a power module, a wiring part, and a case. The case forms a first accommodating portion, a second accommodating portion, and a third accommodating portion above a plane that includes the axis of an output shaft and the axis of a rotary shaft of the rotating electrical machine. The first accommodating portion overlaps the rotating electrical machine when viewed in the axial direction of the rotating electrical machine, and overlaps the power transmission device when viewed in the vertical direction. The second accommodating portion overlaps the rotating electrical machine when viewed in a direction perpendicular to both the vertical direction and the axial direction of the rotating electrical machine, and overlaps the output shaft when viewed in the vertical direction. The third accommodating portion is adjacent to the first accommodating portion and the second accommodating portion, and overlaps the output shaft when viewed in the vertical direction. At least a portion of the power module is disposed in the second accommodating portion or the third accommodating portion.
