Abstract
An adhesive-free multilayered metal laminate having a given thickness which is obtained by bonding a metal sheet having a thin metal film on a surface thereof to a metal foil without using an adhesive; and a process for continuously producing the laminate. The process comprises the steps of; setting a metal sheet on a reel for metal sheet unwinding; setting a metal foil on a reel for metal foil unwinding; unwinding the metal sheet from the metal sheet-unwinding reel and activating a surface of the metal sheet to thereby form a first thin metal film on the metal sheet surface; unwinding the metal foil from the metal foil-unwinding reel and activating a surface of the metal foil to thereby form a second thin metal film on the metal foil surface; and press-bonding the activated surface of the first thin metal film to that of the second thin metal film so that the first thin metal film formed on the metal sheet is in contact with the second thin metal film formed on the metal foil.
