<p>The present invention provides adhesiveless copper clad laminates, which does not have defects on a copper film part due to a pin hole generated at the time of forming a base metal layer on an insulating film by dry plating process, has excellent adhesion between the insulating film and the base metal layer and corrosion resistance, and has a copper film layer having high insulation reliability, and provides a method for manufacturing such adhesiveless copper clad laminates. In adhesiveless copper clad laminates according to the present invention provided by forming a base metal layer directly at least on one plane of an insulating film without having an adhesive in between, and then by forming a copper film layer on the base metal layer, the base metal layer having a film thickness of 3 to 50 nm is formed by dry plating method and mainly contains a chrome-molybdenum-nickel alloy wherein the chrome ratio is 4 to 22 weight %, the molybdenum ratio is 5 to 40 weight %, and the balance is nickel.</p> |
