To provide a film guide roll capable of facilitating maintenance by enabling stable rotation over a long period of time, and to provide an apparatus for manufacturing an optical film using the film guide roll.
A film guide roll 6 includes a roll body 7 which rotates by coming into contact with an outer surface of a resin film 2, a supporting shaft 9 which is arranged in a liquid tank 3, and a bearing 10 for pivotally supporting a roll body 7 on the supporting shaft 9. The bearing 10 includes annular inside permanent magnets 11A and 11B and an annular outside permanent magnet 12. The inside permanent magnets 11A and 11B and the outside permanent magnet 12 are magnetized in such a manner that magnetic poles are directed not only in radial directions but also in opposite directions. The inside permanent magnets 11A and 11B are arranged away from each other in axial directions, and the outside permanent magnet 12 is arranged via an air gap 13 on an outer peripheral side of an axial intermediate position of the inside permanent magnets 11A and 11B.
