摘要：PROBLEM TO BE SOLVED: To provide a method for producing a cellulose ester film which can be peeled off easily even when a film-making speed is high. SOLUTION: In the method for producing the cellulose ester film in which dope prepared by dissolving the cellulose ester in a solvent is cast from a casting die on a casting support, and the film formed by drying the dope cast on the support to a certain extent is peeled off, the content of the cellulose ester in the dope is 10-30 wt.%, and the solvent comprises 70-90 wt.% of methylene chloride and 10-30 wt.% of a lower alcohol.
