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

摘要

PROBLEM TO BE SOLVED: To provide a metal clad-laminate or a resin-coated metal foil in which tight adhesion and smoothness of a surface between an insulating resin composition layer and a metal foil are attained in combination and practical factors such as economical efficiency and handling easiness upon production of a printed wiring board can also be attained and further to provide a printed wiring board and its production method using the metal-clad laminate and the resin-coated metal foil, in which reliability and a circuit formability are excellent and a conductive loss is remarkably low. SOLUTION: In a resin-coated foil comprising an insulating resin composition layer and a metal foil tightly adhered to one or both surfaces of the insulating resin composition layer, at least the side of the insulating resin composition layer is subjected to a surface treatment and the both surfaces of the metal foil are substantially not subjected to roughening-treatment.
