The present invention provides a method for manufacturing a polarizing film, by which, even when a wide raw film is used, it is possible to obtain a polarizing film that achieves excellent optical characteristics as well as uniformity in in-plane optical characteristics. The method includes the steps of dyeing a polymer film; stretching the dyed film; and drying the film that has undergone the dyeing and stretching steps while conveying the film with rolls. In the drying step, at least two rolls are used as the rolls and the film is dried under a condition that a ratio (R/W) of a distance (R) between the adjacent rolls to an initial width (W) of the polymer film is not less than 0.5 and not more than 4.0.
