Abstract
A polarizing glass includes shape-anisotropic metal particles oriented and dispersed in a glass substrate, the concentration of the metal particles having a distribution in which in the travel direction of light in which a polarizing function is exhibited, the concentration is substantially zero near one of the surfaces of the glass substrate and near the other surface, gradually increases from one of the surfaces of the glass substrate to the other surface, becomes a value within a predetermined range in the glass substrate, and then gradually decreases toward the other surface.
