A method for producing an optical film includes forming a stretched film by stretching a thermoplastic resin composition comprising a thermoplastic resin and rubber particles at a stretching temperature; and heating the stretched film at a heat treatment temperature while applying a tensile force in a stretching direction of the stretched film. The stretched film is a biaxially stretched film. The stretching temperature is from Tg to (Tg+20 C.), provided that Tg is a glass transition temperature of the stretched film. The heating reduces a size of the stretched film in the stretching direction by simultaneously decreasing a longitudinal size and a width size of the stretched film, and the heat treatment temperature is from (Tg+10 C.) to (Tg+23 C.)
