PROBLEM TO BE SOLVED: To provide a method for manufacturing a polymeric film, especially a polyimide film improved in surface adhesiveness and having a cleaned surface. SOLUTION: In the method for manufacturing the polymeric film obtained by a casting film-forming method for taking up the polymeric film in a roll form, surface treatment including treatment for applying an ultrasonic wave of 30-500 kHz and treatment for passing air at a flow velocity of 1-300 m/sec is performed. The surface treatment is preferably performed during a process immediately before the polymeric film is taken up in the roll form. This surface treatment is performed at an environment temperature of 0-90°C. COPYRIGHT: (C)2008,JPO&INPIT |
