PROBLEM TO BE SOLVED: To provide a laminated sheet manufacturing method preventing staining or flaw caused by a resin layer having to become an interlaminar insulating layer and constituted so as to obtain a proper energizing route at the time of pressing. SOLUTION: Bands 3, each of which is constituted so that an uncured resin film is arranged to the single surface of a copper foil and a pressure-sensitive adhesive film is arranged to the other single surface thereof, are prepared. The pressure-sensitive adhesive film has a width larger than that of the copper foil with a resin by 10 mm (5 mm at every single side) or more. The bands 3 are folded zigzag, and inner layer sheets 1 and intermediate sheets 2 are alternately held between the bands 3. At this time, the bands 3 are arranged so that the pressure-sensitive adhesive films and the intermediate sheets 2 are opposed mutually and the resin films and the inner layer sheets 1 are opposed mutually. In this state, the whole is pressed by a press processing machine 4 while energizing the copper foils. |
