Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method of a polarizing film which can shorten a dyeing process and largely improve productivity of the polarizing film; and the polarizing film.SOLUTION: A manufacturing method of a polarizing film comprises a step of preparing a PVA resin film including a PVA resin having a saponification degree of 92 to 98.5 mol% as determined in accordance with JIS K 6726; a step of dyeing the PVA resin film; and a step of stretching the PVA resin film. The polarizing film is formed using the PVA resin having the saponification degree of 92 to 98.5 mol% as measured on the basis of JIS K 6726.
