Abstract
Provided is a polarizing element, which is made into an assembly of metal elements by utilizing the fact that the plasmon resonance wavelengths of metal elements are different for the polarization direction of a light to irradiate the metal elements. The sum of the geometrically sectional areas of the metal elements in a plane substantially normal to the propagation direction of the irradiating light is smaller than the area of the irradiated region of the light, and the sum of the absorbing sectional areas of the metal elements in the plasmon resonance wavelengths is five times or more as large as the area of the irradiated region.
