PROBLEM TO BE SOLVED: To provide a method for forming a silicide layer which can improve corrosion resistance of a metal member. SOLUTION: The method for forming the silicide layer on the surface of the metal member consisting of an electroconductive material by electrodeposition, after immersing the metal member into a molten salt bath, comprises employing the molten salt bath provided by heating/melting a salt including Si and an another salt including at least one metal element selected among W, Mo, and Nb, or by heating/melting the salt including Si, a salt including at least one metal element selected among W, Mo, and Nb, and a salt including at least one metal element selected among Cr, Al, and Ni. Thereby, the method can improve corrosion resistance of the metal member, because it can form the silicide layer consisting of a high melting metal, or complexed silicide layer composed of the high melting metal and an oxide-film forming metal.
