PROBLEM TO BE SOLVED: To suppress deterioration of a cellulose ester resin and to improve the mixability/dispersibility of an additive, in a method for obtaining a cellulose ester film for polarizing plate protection by a heat melting method. SOLUTION: In a method for manufacturing a polarizing plate protective film obtained by mixing at least a cellulose ester resin and an organic additive, obtaining an integral molding, and melting it by heating, the molding is a cube having a size of 1 mm×1 mm×1 mm to 20 mm×20 mm×20 mm and the cellulose ester resin is contained in the molding in a state of particles.
