There is provided a high gloss electrodeposited copper foil which can be manufactured in a short time. The electrodeposited copper foil has a fraction of the areas occupied by the {100} plane deviating by 18&#xb0; or less from the &#x3c;001&#x3e; crystal orientation of 10% or more determined by analysis of the surface by electron backscatter diffraction (EBSD) and at least one surface of the electrodeposited copper foil has a glossiness G(20&#xb0;) of 1,500 or more, determined in accordance with JIS Z 8741-1997.

Electrolytic copper foil and manufacturing method therefor

There is provided a metal foil suitable for an electrode substrate for an electronic element, which makes it possible to suppress oxidation of the ultra-smooth surface and also prevent roll scratches when wound in a roll. The metal foil of the present invention is made of copper or copper alloy. The front surface of the metal foil has an ultra-smooth surface profile having an arithmetic mean roughness Ra of 30 nm or less as determined in accordance with JIS B 0601-2001. The back surface of the metal has a concave-dominant surface profile having a Pv/Pp ratio of 1.5 or more, the Pv/Pp ratio being a ratio of a maximum profile valley depth Pv to a maximum profile peak height Pp of a profile curve as determined in a rectangular area of 181 &#x3bc;m by 136 &#x3bc;m in accordance with JIS B 0601-2001.

Metal foil and electronic device

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&#x2014;N bond to the total number of counts on the copper and the C&#x2014;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.

Electrode foil and organic light-emitting device

There is provided an electrode foil, which can show superior light scattering, while preventing short circuit between electrodes. The electrode foil of the present invention comprises a metal foil having a thickness of from 1 &#x3bc;m to 250 &#x3bc;m, wherein the electrode foil comprises, on at least one outermost surface thereof, a light-scattering surface having a Pv/Pp ratio of 2.0 or higher, wherein the Pv/Pp ratio is a ratio of a maximum profile valley depth Pv of a profile curve to a maximum profile peak height Pp of the profile curve as measured in a rectangular area of 181 &#x3bc;m&#xd7;136 &#x3bc;m in accordance with JIS B 0601-2001.
