    Abstract: PROBLEM TO BE SOLVED: To make it possible to improve working efficiency, to lessen the handling of materials and to decrease the kinds of the materials to be used by providing the apparatus with a first cutting roller, take-up device, rotary press and a second die cutting roller having a die packing material around the cut edge. SOLUTION: The conductive foil stock adhered to a supporting body is un- wound from a foil supplying reel 19 and is cut by the die cutting rollers 20 and 21, by which a foil blanking body is generated. A conductive gel with which the supporting body on a gel un-winding roll 23 is coated and the supporting body are laminated integrally with the foil and the supporting body by the rollers 24 and 25, and the supporting body of the gel is peeled by a peeling plate 26. A liner is un-wound from a liner roll 27 and is pressed onto the laminate by the rollers 28 and 19. Another supporting body is un-wound from a spool 32 and is pressed to the laminate, by which a laminar sheet is formed. The sheet if let-off via the die cutting roller 17 and the return pad is cut and formed at the die cutting roller.
