Abstract
In joining a magnesium alloy material(first material) and a steel material (second material), a zinc-plated steel plateplated with zinc (metal C) is used as a steel material, Al (metal D) is added to the magnesium alloy material. Next, eutectic melting of Mg and Zn is caused so as to remove a product produced by the eutectic melting with an oxide filmand impurities from a joint interface. Moreover, an Al—Mg system intermetallic compound such as AlMgand an Fe—Al system intermetallic compound such as FeAlare produced, whereby regenerated surfaces of both materialsandare joined via a compound layercontaining those intermetallic compounds.
