摘要：A polarizer includes a substrate and a fine grid which is made of a metallic

material and is formed on a surface of the substrate. The substrate has a plurality of

projections formed on the surface thereof which have substantially mountain shapes in

sectional view and are arranged at a predetermined height and predetermined pitches. A

metal layer is formed on one inclined surface of each of the mountain-shaped

projections, thereby forming the fine grid. The pitch of the metal layer is set to ½ or

more of the wavelength of light used, and the height of the metal layer is set to ⅕ or

more of the wavelength of the light used.
