摘要：
A process for producing a copper-clad laminate using a copper foil obtained by subjecting the surface of the copper foil to chemical oxidation thereby to form, on the surface, a fine roughness constituted by a copper oxide of a brown to black color and then reducing the copper oxide constituting the fine roughness in an atmosphere in which a reducing gas is present.
