Abstract (en)

A method for manufacturing a dissimilar metal joint member having an excellent corrosion resistance is provided. The method comprises immersing a member having an iron material and Al or an Al alloy material jointed together in a solution containing fluoro complex ions and zinc ions to cause metallic zinc to be deposited in the vicinity of a jointed portion.
