摘要： Electromagnetic waves radiated when a formed polyester film 18 is longitudinally drawn while one surface of the front and rear surfaces of the polyester film 18 is being heated by a radiant heater 30, are composed of such a wavelength band that a thermal energy of 20% or more and 50% or less of the total thermal energy radiated onto the one surface of the polyester film 18 can transmit from the one surface to the other surface. Thereby, even in the case where the film is longitudinally drawn while one surface of the film is being heated in the longitudinal drawing step, a curl is not easily generated in the film.
