The disclosed method comprises applying an adhesive onto both of the opposing edge portions of a carrier (A) being fed by winding-off from a bobbin, adhering a metal foil (B) continuously wound off from a second bobbin to the adhesive-applied side of the face of the carrier in lamination, cutting this laminate into sheets, and stacking orderly the cut laminate sheets; and when the cut and stacked laminate sheets constituted of the orderly stacked laminates comes to rise remarkably at the middle portion thereof, the stack of laminates is roll-pressed on the upper face of the cut and stacked laminate sheets to remove the air from the spaces between the cut laminate sheets and inside of the laminates, and then, curing the adhesive to allow the laminated sheets to adhere together. In particular, the disclosed method is characterized by the carrier-supported copper foil employed in the production of laminate plates, and intends cost reduction in a print substrate production process by improvement of handling property and the production yield.
