PREPREG, METHOD OF MANUFACTURING THE SAME AND METHOD OF MANUFACTURING LAMINATED SHEET

摘要

PROBLEM TO BE SOLVED: To provide a prepreg capable of uniformizing the resin amount of the insulating layer of a laminated sheet and capable of preventing the adhesion of a resin to a molding plate. SOLUTION: A prepreg 1 is used in forming a laminated sheet by superposing a metal foil 2 on the prepreg and molding the whole under pressure while passing a current through the metal foil 2 to generate heat. The resin amount of an end part 3 is adjusted so that the thickness of the end part 3 becomes equal to or less than that of a part 4 other than the end part 3. Pressure can be applied almost uniformly by heating and pressure molding in the production of the laminated sheet. The outflow of an excessive resin 8 can be prevented.
