A manufacturing apparatus is provided for manufacturing a tubular resin film of high quality and little thickness variations, which is stretched and given an orientation, and suitable as retardation film or the like. It comprises a stretching section ( 6 ) for stretching the tubular resin film ( 20 ), and a maintaining section ( 7 ) for maintaining a shape of said tubular resin film ( 20 ) stretched. Further, said stretching section ( 6 ) is arranged to apply a stretching force to said tubular resin film for longitudinally and/or circumferentially stretching said tubular resin film ( 20 ). |
