Abstract
Provided is a wire grid polarization plate that has heat resistance and excellent polarization properties, and has durability even in a thin wire structure with a small pitch, and an optical apparatus and a manufacturing method of a polarization plate. A periodic lamellar structure is formed with a material forming arrangement by self-assembling performance, and then, is metallized, and thus, metal wires arranged at a small pitch are prepared, and the obtained wires are fixed by a dielectric material.
