PROBLEM TO BE SOLVED: To provide a manufacturing method capable of easily providing a laminate metal strip of predetermined roughness. SOLUTION: In this manufacturing method of the laminate metal strip by pressing and bonding a first metal strip 4 and a second metal strip 5 between rolls 8 after a third metal layer similar to or dissimilar from the first metal strip 4 or the second metal strip 5 is stuck to at least one surface side of a bonded surface of the first metal strip 4 and a bonded surface of the second metal1 strip 5 through activation, for example, by a dry film deposition device 6 in a vacuum vessel, the surface of at least one of the rolls 8 is a adjusted to form a roughened surface of 0.5-20μmRz. |
