Abstract

See full text

Provided is a copper-clad laminate in which a copper foil and a resin are joined together with high heat-resistant adhesion force though a fluororesin is used. This copper-clad laminate includes a surface-treated copper foil including a copper foil and a zinc-containing layer on at least one surface of the copper foil; and a sheet-shaped fluororesin on the zinc-containing layer side of the surface-treated copper foil. The zinc-containing layer is composed of Zn and a transition element M having a melting point of 1200° C. or more. When the interface between the copper foil and the zinc-containing layer is subjected to elemental analysis by GD-OES, the emission intensity ratio IZn/ICu of the emission intensity of Zn to that of Cu is 3.0×10−3 or less, and the emission intensity ratio IZn/IM of the emission intensity of Zn to that of the transition element M is 0.30 to 0.50.
