According to an aspect of the present invention, there is a provided a method for manufacturing a cellulose resin film comprising: ejecting a molten cellulose resin from an outlet (ejection port) of a die in a form of sheet; and casting the sheet-form cellulose resin on a drum, wherein a difference between a temperature Tl of the sheet-form cellulose resin ejected from the die and a temperature T2 of the sheet-form cellulose resin cast on the drum falls within 20 degrees centigrade or less. According to the aspect, the proceeding of the cooling and solidification of the sheet-form cellulose resin can be controlled, and thereby, a film having a small film-thickness distribution and excellent in flatness of the surface can be obtained. |
