To provide a copper-clad laminate which maintains adhesion between a resin film and a conductor layer and which suppresses the occurrence of wrinkles. A copper-clad laminate has a base film containing a thermoplastic resin, an underlying metal layer film-formed on a surface of the base film by a dry plating method, and a copper layer film-formed on a surface of the underlying metal layer.
