Abstract:
A polarization element according to the invention includes a substrate, a metal layer and an absorber layer formed on the substrate to form a stripe in a plan view and stacked in a thickness direction of the substrate, a first dielectric layer formed on a surface of the metal layer and a second dielectric layer formed on a surface of the absorber layer. The first dielectric layer is made of an oxide of a metal constituting the metal layer, and the second dielectric layer is made of an oxide of a material constituting the absorber layer.
