WIPO Patent Application WO/2019/027174

Kind Code:

A1

Abstract:

An embodiment of the present invention provides a copper foil, which comprises a copper layer having a matte surface and a shiny surface and an anti-rusting film disposed on the copper layer and has a residual stress of 0.5-25 Mpa based on an absolute value, the copper layer having crystalline faces, wherein in the sum of texture coefficients (TCs) of (111) face, (200) face, (220) face, and (311) face, which are the crystalline faces of the copper layer, the proportion [TCR(220)] of the texture coefficient of the (220) face [TC(220)] is 5-30%.
