The foil thus formed is wound into a coil. The thermoplastic polyimide-coated copper-nickel alloy foil and a SUS 304 foil are stacked on each other, with the SUS 304 foil being in contact with the thermoplastic polyimide side of the copper-nickel alloy foil, between heating and bonding rolls. Then, the temperature of the roll at the SUS 304 foil side is set to 220 deg.C and that of the roll at the alloy side of the thermoplastic polyimide-coated copper nickel alloy foil is set to 210 deg.C.  By setting the rollers to different temperatures, the roller contact time can be secured for each of the metal foils. Then, the two metal foils are laminated and a provisional bonded product of a metal foil polyimide laminate can be obtained. After that, the provisional bonded product is pressed to obtain a metal foil polyimide laminate sheet.
