A polarizing plate having an excellent optical property and a method of manufacturing the same. The polarizing plate includes: a transparent substrate 11 transmitting light in a used bandwidth; an absorbing layer 12 having at least a metal-containing semiconductor layer containing a metal, the absorbing layer being arranged as a one-dimensional lattice shaped wire-grid structure having a pitch smaller than the wavelength of the light in the used bandwidth; a dielectric layer 13 arranged as a one-dimensional lattice shaped wire-grid structure having a pitch smaller than the wavelength of light in the used bandwidth; and a reflective layer 14 arranged as a one-dimensional lattice shaped wire-grid structure having a pitch smaller than the wavelength of light in the used bandwidth, wherein the absorbing layer 12, the dielectric layer 13 and the reflective layer 14 are layered on the transparent substrate 11 in this or reversed order.
