PURPOSE: To lessen the defective products generated by adhesion of foreign matters to the surface of a bonding agent when an additive method printed wiring board's bonding agent-adhering laminated sheet is processed.

CONSTITUTION: A metal-foil-coated adhesive applied laminated sheet is formed by sticking an adhesive sheet, obtained by applying an adhesive agent on a sheet of mold-releasing treated metal foil, to a laminated sheet. A hole is perforated in the metal-foil-coated laminated sheet, a circuit is formed, and then metal foil is peeled off.
