Abstract
Provided is an inorganic polarizing plate having a wire grid structure including: a transparent substrate; and grid-shaped protrusions arranged on the transparent substrate at a pitch shorter than a wavelength of light in a use band, in which the grid-shaped-protrusion includes, in order from the transparent substrate side, a reflection layer and a reflection suppressing layer which includes a dielectric material and a non-dielectric material and of which a content of the non-dielectric material increases as a separation from the reflection layer increases. In addition, provided are a method of manufacturing the inorganic polarizing plate and an optical instrument including the inorganic polarizing plate.
