Claim:
1. A method of manufacturing a wire grid polarizer, the method comprising: preparing a stamp having a nanostructure body at one surface and forming a mask layer with anisotropic vapor deposition at the one surface; forming a metal film on a substrate; transferring the mask layer onto the metal film; and patterning the metal film into metal lines by removing a portion that is not covered with the mask layer with dry etching, wherein the nanostructure body comprises a plurality of protruding portions, the forming of a mask layer with anisotropic vapor deposition comprises forming a mask layer at an upper surface and one side surface of each of the plurality of protruding portions by performing anisotropic vapor deposition in a direction that is inclined in a thickness direction of the stamp, and the mask layer that is transferred onto the metal film comprises a flat portion with a constant thickness and a protrusion that contacts one side edge of the flat portion.
