摘要： A method of manufacturing a polarizer is provided that makes it possible to manufacture a polarizer prevented from curling even when a liquid is brought into contact with a hydrophilic polymer film by being sprayed. A method of manufacturing a polarizer includes a swelling step A for swelling a hydrophilic polymer film 1 by bringing it into contact with a swelling liquid 2, a dyeing step B for dyeing the hydrophilic polymer film 1 by bringing it into contact with a dye liquid 3 containing a dichroic material, and a crosslinking/stretching step C for crosslinking the hydrophilic polymer film 1 by bringing it into contact with a crosslinking liquid 4 and further stretching it. In the method, the contact with the swelling liquid in the swelling step A is carried out in the gas phase by spraying the swelling liquid 2 onto both surfaces of the hydrophilic polymer film 1.
