A film transfer method, according to one embodiment of the present invention, is a film transfer method for transferring a film adhered to a substrate to a roller, in a state where a first adhesive force between the roller and the film and a second adhesive force between the film and the substrate are substantially the same, the film transfer method comprising: a transporting step of transporting, in a first direction, the substrate and the film having a first adhesive surface formed on one surface thereof adhered to the substrate; a tight contact step of bringing the front end portion of a second adhesive surface, formed on the other surface of the film to be transported, into tight contact with the roller which rotates in a first rotational direction; and a transfer step of enabling a front end adhesive surface of the first adhesive surface to be peeled off from the substrate while enabling, at the same time, the front end portion of the second adhesive surface to be adhered to the roller, and allowing the substrate to be continuously transported in the first direction so as to enable the film to be peeled off from the substrate and to be transferred to the roller at the same time, wherein a first weak adhesive force which is weaker than the second adhesive force may be formed between the front end adhesive surface and the substrate.
