The object of the present invention is to realize a high degree of polarization without increasing the aspect ratio of the wire, and to have excellent reflection characteristics in the visible light region, particularly in the range of about 100 nm before and after centering on a maximum visibility wavelength of 555 nm, thereby enabling easier processing. An object of the present invention is to provide a wire grid polarizer. SOLUTION: A substrate 1, a metal wire 10 arranged in a lattice pattern on the substrate 1, and a multilayer wire 11 laminated on the metal wire 10 in two or more layers are provided, and the multilayer wire 11 is 1.00. A low refractive index layer composed of a low refractive index material having a refractive index n 1 of 1.65 or less and a high refractive index n 2 provided on the low refractive layer and having a refractive index n 2 of 1.80 or more and 4.50 or less. A laminate including a high refractive index layer made of a refractive index material, wherein the low refractive index layer and the high refractive index layer are selected from elements having a fluoride boiling point of 250 degrees or less, and oxidation of the elements Formed of a material selected from any of oxides, nitrides, sulfides, and carbonates.
