Abstract: [TECHNICAL PROBLEM]Provided a polarizing film which comprising a substrate and a PVA-based resin, wherein it has good adhesion between the substrate and the PVA-based resin to allow the PVA-based resin to become less likely to be peeled off from the substrate during stretching and/or conveyance, and exhibits excellent appearance.[SOLUTION]The polarizing film is obtained by providing a layer of a PVA-based resin on a substrate and stretching the substrate and the PVA-based resin layer together. The PVA-based resin contains a modified PVA, wherein the modified PVA exists in an amount allowing a modification rate with respect to the entire PVA-based resin to be in a range of 0.04 mol % to 1.4 mol %.
