Abstract: A method for manufacturing a laminated film and an apparatus for manufacturing a laminated film obtains a laminated film including a cured layer having a uniform thickness at the time of manufacturing a laminated film obtained by sandwiching the cured layer obtained by curing an actinic ray curable-type resin between two sheets of films. Steps include forming a coating film of a coating solution containing an actinic ray curable-type resin on the surface of a first film while continuously transporting the first film, laminating a second film on the coating film while continuously transporting the second film, and forming a cured layer of the coating film by irradiating the coating film with an actinic ray while continuously transporting the coating film by sandwiching the coating film between the first film and the second film, in a state where the first film is being wound around a backup roller.
