Abstract
There is provided an electrode foil that can form an organic electroluminescent device having a high external quantum efficiency despite the presence of the organic nitrogen compound at the interface of a metal foil and a reflective layer. The electrode foil of the invention includes a metal foil made of copper or copper alloy and a reflective layer provided on at least one surface of the metal foil. The electrode foil has an organic nitrogen compound at the interface between the metal foil and the reflective layer in such an amount that the ratio of the number of counts on the C—N bond to the total number of counts on the copper and the C—N bond: CN/(CN+Cu) in the organic nitrogen compound is 0.4 or less determined by time-of-flight secondary ion mass spectrometric analysis (TOF-SIMS) of the interface.
