Abstract
To establish a technique of further improving the oxidation resistance of the glossy surface of a copper foil that has a composite layer containing chromium, zinc, and phosphorus on its glossy surface is achieved by a copper foil having excellent oxidation resistance characterized by a composite layer containing chromium, zinc, phosphorus, and nickel formed on the glossy surface of the foil and also to a method of manufacturing the same by electrolysis.
