Left and right side members of a frame, a propeller shaft, and an exhaust pipe extend in a vehicle longitudinal direction through a region in the cabin section that is below the passenger compartment. The battery is disposed in a region of at least one of the cabin section and the cargo section, and the region is above the side members, the propeller shaft, and the exhaust pipe. The high-voltage electrical unit is disposed in a region in the cabin section that is below a rear-row seat and beneath a floor of the passenger compartment.
