Abstract
There is provided a magnesium alloy molded product being excellent in corrosion resistance. The magnesium alloy molded product being excellent in corrosion resistance and capable of being easily recycled is manufactured by forming an aluminum layer on a surface of a magnesium alloy molded body and then forming an anticorrosive film layer on the surface of the aluminum layer. In addition, a magnesium alloy molded product being excellent in corrosion resistance and having a brilliant anticorrosive structure is manufactured by forming a transparent anticorrosive film consisting of an organic acid amine salt on a cut surface of a magnesium alloy molded body and then forming a transparent painted film on the transparent anticorrosive film.
