The invention provides a joint body of dissimilar aluminum alloy materials and a vehicle doo. In the joint body of the dissimilar aluminum alloy materials, first and second aluminum-magnesium-silicon type aluminum alloy materials are welded to an aluminum-magnesium type aluminum alloy material, so that the improvement of position precision and the adjustment of accumulated size errors can be achieved, and the degree of freedom of the design is improved. The joint body of the dissimilar aluminum alloy materials is formed in a manner that the aluminum-magnesium type aluminum alloy material and the first aluminum-magnesium-silicon type aluminum alloy material are welded through electric arc welding, and the aluminum-magnesium type aluminum alloy material and the second aluminum-magnesium-silicon type aluminum alloy material are welded through friction stir welding.
