Abstract: An object of the present invention is to provide a method for producing a metal laminate material that maintains sufficient bonding strength and has superior production efficiency. A method for producing a metal laminate material by bonding two sheets, one sheet composed of a material M1 and the other sheet composed of a material M2, wherein each of M1 and M2 is a metal or alloy comprising any one or more selected from the group consisting of Mg, Al, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Nb, Mo, Pd, Ag, In, Sn, Hf, Ta, W, Pb, and Bi, comprises the steps of subjecting the faces of the two sheets to be bonded to sputtering treatment with inert gas ions under vacuum such that oxide layers on surface layers remain; temporarily bonding the two sheets by roll pressure bonding; and conducting a thermal treatment to thereby bond the two sheets, and, when Tm1>Tm2 where Tm1 (K) is the melting point of M1 and Tm2(K) is the melting point of M2, the temperature of the thermal treatment is 0.45Tm2 or more and less than 0.
