Abstract
An aspect of the present invention is a method for producing a resin film, including a casting step of casting a resin solution containing a transparent resin from a casting die onto a running support to form a cast membrane, and a releasing step of releasing the cast membrane from the support, wherein, in the casting step, a velocity at which the resin solution is discharged from longitudinally opposite ends of a discharge port of the casting die is 0.95 times to 1.5 times a velocity at which the resin solution is discharged from a longitudinally central portion of the discharge port of the casting die.
