Abstract: The present invention provides a method for manufacturing graphene, said graphene, and an apparatus for manufacturing same. The method for manufacturing graphene comprises the steps of: loading a catalytic metal layer into a chamber; applying tensile force to the catalytic metal layer; and forming graphene on the catalytic metal layer by supplying a carbon source into the chamber while the tension is applied to the catalytic metal layer. Therefore, the size of the grains on the catalytic metal layer can be increased by applying tension to the catalytic metal layer, and high quality uniform graphene can be grown through the use of the catalytic metal layer.
