Copper foil composite
A copper foil composite comprising a copper foil and a resin layer laminated thereon, wherein equation 1: (f3×t3)/(f2×t2)=>1 is satisfied when t2 (mm) is a thickness of the copper foil, f2 (MPa) is a stress of the copper foil under tensile strain of 4%, t3 (mm) is a thickness of the resin layer,...
