METAL-CLAD LAMINATE AND METHOD FOR PRODUCING THE SAME, METAL FOIL WITH RESIN AND PRINTED WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide a metal-clad laminate enabling a printed wiring board having further reduced loss upon signal transmission to be manufactured, and to provide a method for producing the metal-clad laminate.SOLUTION: The metal-clad laminate is provided that includes: an insulating layer 12 which contains a phenylene ether compound and is cured; a metal layer 13 joined to the insulating layer 12; and an intermediate layer 17 interposed between the insulating layer 12 and the metal layer 13 and containing a silane compound. The metal layer 13 has a joining surface 15 joined to the insulating layer 12 through the intermediate layer 17. A ten-point average roughness Rz of the joining surface 15 is 0.5 μm or more and 4 μm or less.SELECTED DRAWING: Figure 1
