To provide a method of manufacturing a laminate film which satisfies improvement of a tenacity of an applied film, adhesion between a base material of a thermoplastic resin film and the applied layer, and a pot life of application liquid at the same time, and shows superiority in applicability and a production yield.
The method of manufacturing the laminate film satisfies the following items (1)-(3): (1) a flame retardation layer is mounted on at least one surface of the base material of the thermoplastic resin film, (2) a content of an isocyanate compound of the flame retardation layer is 3 to 10 pts.wt., and (3) a solid content of the application liquid is less than 35 wt.% when the flame retardation layer is applied. A solar cell and back light are constructed by using the laminate film.
