Provided is a polarizing film that has good adhesion between a base material constituting a polarizing film and a PVA-based resin, and that the PVA-based resin is hardly peeled off from the base material in a stretching process or a transporting process. To do. A polarizing film obtained by providing a PVA resin layer on a substrate and stretching the substrate and the PVA resin layer integrally, wherein the PVA resin contains a modified PVA and is modified. PVA is a polarizing film in which the modification ratio based on the entire PVA resin is present in an amount such that it is 0.04 mol% to 1.4 mol%. [Selection figure] None |
