A graphene manufacturing device using Joule heating includes: a chamber having a space provided therein so as to synthesize graphene; and a first roller portion and a second roller portion disposed inside the chamber to be spaced from each other such that same support a catalyst metal penetrating the interior of the chamber and are supplied with an electric current for graphene synthesis, thereby Joule-heating the catalyst metal. In order to compensate for a temperature deviation of the catalyst metal passing between the first roller portion and the second roller portion, a first area of the catalyst metal, which is close to the first roller portion, and a second area of the catalyst metal, which is close to the second roller portion, are disposed to have movement paths facing each other.
