THERMALLY FUSIBLE POLYIMIDE FILM AND POLYIMIDE METAL LAMINATE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a thermally fusible polyimide film excellent in adhesion to metal, and a polyimide metal laminate using the thermally fusible polyimide film with high releasing strength between the polyimide film and a metal layer.SOLUTION: In a thermally fusible polyimide film, a thermally fusible polyimide layer includes 10-30 mass% of filler having an average particle diameter of 0.5 μm or less.
