Abstract
A method for producing a polarizing element includes the steps of : forming a coating film of a metal on a glass substrate; forming an island-shaped film composed of a metal halide on the glass substrate by partially removing the coating film and also halogenating the metal; forming needle-shaped particles of the metal halide by stretching the glass substrate through heating to elongate the island-shaped film; and forming needle-shaped metal particles composed of a metal by reducing the metal halide of the needle-shaped particles.
