摘要： PROBLEM TO BE SOLVED: To provide a method of forming a multilayered film without causing any fine coating unevenness in the formation of a resin layer by applying a plurality of coating liquids different in viscosity. SOLUTION: A resin layer forming apparatus is provided with: back-up rollers 13, 23 for transporting a film at a prescribed speed; a coating means for discharging the resin coating liquid to the film on the surface of the back-up roller; and supply rollers 11, 21 for supplying the film to the back-up rollers. In the resin layer forming apparatus 100 for forming a resin layer using a most viscous resin coating liquid, the film transporting speed of the supply roller 11 nearest to a coating means is fixed to a prescribed value, the film transporting speed of the back-up roller 13 is controlled to follow the supply roller 11 and the film transporting speed of the supply roller 21 in other resin layer forming apparatus 200 is controlled in proportion to the expansion and contraction of the film.
