    Abstract: PROBLEM TO BE SOLVED: To provide a copper-clad laminate which shows less degrading of adhesion between a resin layer containing a liquid crystal polymer and a copper foil even when stored under high temperature and humidity atmosphere. SOLUTION: In the method for producing the copper-clad laminate wherein a resin layer containing a liquid crystal polymer adheres to a surface of the copper foil, the copper-clad laminate which can sufficiently maintain excellent adhesion even when stored under high temperature and humidity atmosphere is obtained by using a copper foil of which the surface has 0.4 or more of a ratio of nickel concentration to copper concentration (C Ni /C CU ) and has substantially no silicon detected when measured with X-ray photoelectron spectroscopy. The liquid crystal polymer is preferably a liquid crystal polyester having a specific structural unit. The copper-clad laminate can appropriately be used for a flexible printed wiring board or the like. COPYRIGHT: (C)2010,JPO&INPIT
