ものである。(F) Effects of the Invention The thin metal sheet for forming according to the present invention has a compound represented by the general formula (1), which is a lubricating substance, firmly attached to the surface of the thin metal sheet, so that it does not have lubricity during handling. The compound represented by formula (I) is less likely to fall off, and the compound represented by formula (I) is evenly and uniformly adhered to the surface of the metal sheet. Therefore, when performing squeeze forming using a forming die, this forming metal thin plate does not inhibit sliding with the forming die and exhibits good lubricity, so stress concentration does not occur and cracks in the metal thin plate do not occur. This has the effect of improving the production yield of molded products by squeeze molding and the like.
