The invention provides a vehicle, a heat exchange plate and a battery pack capable of reducing the temperature rise of a central area of a vehicle-mounted battery. The vehicle is provided with the heat exchange plate having a coolant layer and a refrigerant layer; a battery module group which is provided with a plurality of battery modules and is arranged along the first surface of the heat exchange plate; a vehicle body that houses the heat exchange plate and the battery module; first and second wheels coupled to the vehicle body; and a motor that drives the first wheels by the electric powersupplied from the battery module group. The coolant layer has a first region in plan view as viewed from the direction in which the first surface and the second surface are arranged. The refrigerantlayer has a second region in plan view. The battery module group is provided with a third region on the first surface in plan view, the second region of the refrigerant layer is smaller than the firstregion of the coolant layer, at least a portion of the second region of the refrigerant layer is disposed so as to overlap the first region of the coolant layer, and the center of the third region ofthe battery module group is disposed so as to overlap the second region of the refrigerant layer.
