Claim Text:
1. A method of obtaining graphene, the method comprising: preparing a graphene forming structure of which a first graphene is formed on one surface and a second graphene is formed on another surface, and that comprises two metal catalyst members and an intermediate member disposed between the two metal catalyst members; disposing a first carrier and a second carrier on the first graphene and the second graphene, respectively; and removing the two metal catalyst members by applying an etchant to a side surface of the graphene forming structure while winding up the first carrier and the second carrier by respectively rotating a pair of rolls formed to face each other, wherein the first graphene is formed on one surface of one of the two metal catalyst members, and the second graphene is formed on one surface of the other one of the two metal catalyst members.
