摘要: A film casting method of forming a plastic film in which a macromolecular solution (1) is made to spread onto a running endless support of a metal plate (2), and thus formed film is dried. The support is heated for drying by using only a radiation heat source (3) from the rear surface side of the support in a period before a solvent content in said film is decreased to be not more than 35 weight percent.
