Abstract
The present invention relates to a metal foil having a rough surface, a carrier-attached metal foil including the metal foil, and a printed circuit board manufactured using the metal foil. The rough surface is naturally formed during formation of the metal foil. The formation of the rough surface allows the metal foil to have a high adhesive strength to an insulating resin substrate and enables the manufacture of a printed circuit board with improved efficiency.
