摘要： Disclosed are composite copper foil and a method for manufacturing composite copper foil which has a high adhesion performance with a base material while maintaining the transmittance of the base material. A rolled copper foil, a copper plating layer formed on at least the side surface of the rolled copper foil, and a rough copper plating layer formed on the copper plating layer and having rough particles in which the average particle size is 0.05-0.30 um are included. The ratio of a maximum particle size and a minimum particle size of the rough particle is 65% or less. The rough particles are continued on the copper plating layer over the distance of 20 um or greater on the cut surface in which the rough copper plating layer is cut in a thickness direction.
