A composite copper foil excellent in conductivity and surface shape, having high strength and able to be used for applications such as high frequency transmission circuits and a method of production of the same are provided. A composite copper foil characterized by having a copper foil on at least one surface of which a copper and/or silver smoothing layer is provided. Further, producing this by processing an ingot having a copper alloy to a foil having a desired thickness by rolling, then forming on at least one surface of the processed copper alloy foil a smoothing layer by copper plating and/or silver plating. Alternatively, producing this by processing an ingot having a copper alloy to a foil having a thickness of an intermediate size by rolling, forming on at least one surface of the foil a smoothing layer by copper plating and/or silver plating, then rolling the result to a foil having a desired thickness or applying heat treatment or applying heat treatment and rolling to thereby make the thickness of at least the copper and/or silver plating layer at the surface of the foil 0.01 μm or more. Further, a high frequency transmission circuit characterized by being prepared using the above composite copper foil or the composite copper foil produced by the above method of production.
