Abstract

One embodiment of the present disclosure provides a copper foil having a first surface and a second surface and including a copper film having a matte surface facing the first surface and a shiny surface facing the second surface; and a protective layer disposed on the copper film, wherein the copper foil has a specular reflectivity of 1.0 to 30.0 on the first surface. The specular reflectivity refers to a value obtained by subtracting a brightness index measured in a specular component excluded (SCE) mode from a brightness index measured in a specular component included (SCI) mode, and is measured using a colorimeter.
