A method for manufacturing a film, wherein a molten resin is pinched between a TR external peripheral face (124) and a CR external peripheral face (126) while the relationships RyTR <= 0.2S, RyCR <= 0.2S, and 1.5 <= RyTR/RyCR <= 4.0 are satisfied, the relationship 101 <= ETR/ECR <= 103 is satisfied, and the relationship 1°C <= (TCR - TTR) <= 100°C is satisfied, where RyTR is the surface roughness, ETR is the elasticity, and TTR is the temperature of the TR external peripheral face (124) of a touch roll (104), and RyCR is the surface roughness, ECR is the elasticity, and TCR is the temperature of the CR external peripheral face (126) of a cast roll (102). The uniformity of pinching by the touch roll and the cast roll can thereby be stabilized, the stability of peeling from the touch roll can be enhanced, and the film can be endowed with highly precise flatness. |
