Zusammenfassung:	PURPOSE:To obtain a dense and smooth aluminum allay laminated plated steel in which the elusion and precipitation of base metal are prevented in the case aluminum plating is applied to the upper layer and good in the adhesion with substrate base metal as well as excellent in sacrificial corrosion inhibition capacity. CONSTITUTION:A steel is applied with manganese plating from an ordinary aq. soln. bath, on which the plating of an aluminum allay contg. at least one kind selected from a group constituted of Mn, Co, Ni, Zn, Cr, Pb, Ti and Sn is applied in such a manner that the concn. inevitably included is regulated to the lower limit and 30% concn. of the elements intentionally added is regulated to the upper limit from a molten salt bath, by which the objective aluminum alloy laminated plated steel can be obtd.
