PROBLEM TO BE SOLVED: To provide a method for producing a cellulose acylate film, by which the occurrence of plate-out can be suppressed and the cellulose acylate film prevented from yellowing can be produced. SOLUTION: A flow casting film 24a is formed by flow casting, on a flow casting drum 82, a dope 24 containing compound having a skeleton represented by formula (I) and a cellulose acylate wherein the amounts of calcium, magnesium and sulfuric acid are each adjusted to be in a prescribed range or have a prescribed relation. The flow casting film 24a is peeled off from the flow casting drum 82 and dried to obtain the cellulose acylate film 62. COPYRIGHT: (C)2009,JPO&INPIT
