A joined body of dissimilar aluminum alloy materials includes a first Al—Mg—Si aluminum alloy material, a second Al—Mg—Si aluminum alloy material, and a single Al—Mg aluminum alloy material. The joined body of dissimilar aluminum alloy materials is formed by welding the first Al—Mg—Si aluminum alloy material and the second Al—Mg—Si aluminum alloy material to the single Al—Mg aluminum alloy material. The Al—Mg aluminum alloy material and the first Al—Mg—Si aluminum alloy material are joined by arc welding. The Al—Mg aluminum alloy material and the second Al—Mg—Si aluminum alloy material are joined by friction-stir welding.
