  A dope ( 36 ) containing TAC and plasticizer is produced. Foreign materials in the dope ( 36 ) are filtrated by a filtration device ( 57 ). In the filtration device ( 57 ), the dope ( 36 ) flows from an outer passage ( 58 a ) to an inner passage ( 58 b ) through a filter ( 59 ). The filter ( 59 ) has a first layer ( 59 a ), a second layer ( 59 b ), and a third layer ( 59 c ), which are formed of sintered metal fibers. An average diameter of the sintered metal fibers of the first layer ( 59 a ) is 8 mm, that of the second layer ( 59 b ) is 4 mm, and that of the third layer ( 59 c ) is 20 mm. The filter ( 59 ) is roasted 2 hours at 400° C. and reused. Breakages from the sintered metal fibers in the first and second layers ( 59 a , 59 b ) are filtrated in the third layer ( 59 c ).

  A dope containing TAC is cast onto a belt. When having self-supporting properties, the dope is peeled as a wet film ( 46 ) from the belt, and transported into a tenter dryer ( 60 ). A preheating is made in an entrance section ( 80 ), and a stretching is made in a stretching section ( 81 ). In a relaxation section ( 82 ), the width of the film was becomes shorter, and in the exit section ( 83 ), the width was kept to be uniform and transported from the tenter dryer ( 60 ) as a film ( 61 ). When a width of the wet film ( 46 ) right before the stretching is L1 (mm), a maximum width of the wet film ( 46 ) in the stretching is L2 (mm) and a width of the wet film ( 46 ) right after the relaxation is L3 (mm), the stretching and relaxation are performed so as to satisfy a following formula, 3<( L 2− L 3)/ L 1×100<9
