NOVELTY - The utility model belongs to the technical field of electric heating film, especially relates to a graphene electro-thermal film, comprising a substrate, a graphene layer, an electrode layer and a resistance adjusting layer; the substrate comprises a heating function area and a non-functional area set at two sides of the heating function area, the heating function area comprises a main body area and a resistance adjusting area set at two sides of the main body area, the resistance adjusting area is set between the main body area and the non-functional area; the electrode layer comprises a first electrode and a second electrode oppositely set, the graphene layer is set in the main body area and the resistance adjusting area, the first electrode and the second electrode are electrically connected with the graphene layer, the resistance adjusting layer is set in the resistance adjusting area; the resistance adjusting layer is used for compensating the power density of the resistance adjusting area; one of the first electrode and the second electrode is a positive electrode, and the other one is a negative electrode. In the utility model, the edge temperature can be improved by setting the resistance adjusting area, when splicing, the non-functional area of the non-heating function located at the splicing part is affected by the resistance adjusting area, it can reduce the generation of the cold area, the temperature difference of the splicing part is obviously reduced.
