PROBLEM TO BE SOLVED: To provide copper foil provided with a resistance layer which has a high sheet resistance value, and is hardly dissolved simultaneously with copper, and to provide a production method therefor. SOLUTION: The copper foil with a resistance layer is used so as to be laminated with an insulating base material, and at least one side has a surface roughness of 3 to 6μm by a 10 point average roughness prescribed by JIS B 0601. A resistance layer consisting of an electrically conductive material having an electrical resistivity of 0.05 to 2μΩm at 298K is formed on one side or both sides of the substrate copper foil to a thickness of 10 to 300 mg/m<SP>2</SP>.
