摘要:
Object is to provide a surface-treated copper foil free from chromium in the surface-treatment layer and excellent in peel strength of a circuit and chemical resistance against to degradation of the peel strength after processing into a printed wiring board. To achieve the object, the surface-treated copper foil having a surface-treatment layer on a bonding surface of a copper foil for manufacturing a copper-clad laminate by laminating it to an insulating resin substrate has the surface-treatment layer formed by depositing a metal component having high melting point not lower than 1400° C. by dry process film formation method to the bonding surface of the copper foil after the cleaning treatment and further depositing a carbon component to the surface.
