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. The underlying metal layer has a mean thickness of 0.3 to 1.9 nm. Since the underlying metal layer has a mean thickness of 0.3 nm or more, it is possible to maintain adhesion between the base film and a conductor layer. Since the underlying metal layer has a mean thickness of 1.9 nm or less, it is possible to suppress an increase in the temperature of a film during film-forming of the underlying metal layer, and it is possible to suppress the occurrence of wrinkles.
