Provided are a method of producing a layered film, the method comprising a resin layer formation step (S10) consisting of a coating step of applying a solution containing a polyvinyl alcohol resin onto one surface of a base material film to form a resin coated layer, and a drying step of drying the above-described resin coated layer to form a resin layer, wherein in the above-described coating step, un-coated portions on which the above-described solution is not applied are formed in regions each being 0.5 cm or more separated inward from each of the above-described base material film's edges opposing each other along the width direction, a method of producing a polarizing layered film using the layered film, and a method of producing a polarizing plate using the polarizing layered film. According to the present invention, a method of producing a polarizing plate with good productivity while preventing a warping phenomenon is provided.
