Abstract

A production method includes a rolling step of obtaining a laminated plate by clad rolling first and second metallic plates in a superposed manner at a rolling reduction of 25 % to 85 %, a surface activation treatment step of subjecting at least joint scheduled surfaces of the laminated plate 20 and a third metallic plate 3 to a surface activation treatment in vacuum, and a cold pressure welding step of, after performing the surface activation treatment, in vacuum, cold pressure welding the laminated plate 20 and the third metallic plate 3 in a superposed manner that the joint scheduled surfaces thereof are in contact with each other by and between a pair of pressure rolls 44 and 44 so that a rolling reduction becomes 0.1 % to 15 %.
