Abstract
The present invention relates to a manufacturing method for single crystalline metal foil including: thermally treating poly-crystalline metal foil positioned to be spaced apart from a base to manufacture single crystalline metal foil, and a single crystalline metal foil manufactured thereby. According to the present invention, single crystalline metal foil having a large area may be obtained by thermally treating the poly-crystalline metal foil under a condition at which stress applied to the poly-crystalline metal foil is minimized.
