Abstract

A surface-treated copper foil includes a treated surface, where the peak extreme height (Sxp) of the treating surface is 0.4 to 3.0 μm. When the surface-treated copper foil is heated at a temperature of 200° C. for 1 hour, the ratio of the integrated intensity of diffraction peak of () plane to the sum of the integrated intensities of diffraction peaks of () plane, () plane, and () plane of the treating surface is at least 60%.
