One of the methods of manufacturing a phase difference film of the present invention provides a strip-shaped phase difference film which has a delayed phase axis that is inclined with respect to the longitudinal direction, an NZ coefficient closer to 1 than conventional values, and a weak biaxial stretchability (has strong uniaxial stretchability). In the manufacturing method is used a pair of clip sets that grip both peripheral edge parts of the strip-shaped raw film, and a heating and stretching apparatus having a stretching zone. At the time the clip sets grip the raw film, the traveling speed of the pair of clip sets is the same. The stretching zone has a first segment in which the traveling speed of one of the clip sets that have traveled into the zone is successively reduced, and after the first segment, a second segment in which the traveling speed of the above one of the clip sets that have traveled via the first segment is successively restored.
