A polarizing elementhas a first undulating structure in which a plurality of linear first recessesare formed parallel to one another in one surface of a transparent substrate, and a dielectric layermade from silicon dioxide is formed on the surface of the first undulating structure to produce a second undulating structure. The second undulating structure has formed therein second recesseshaving a width W and a depth H, with second projectionshaving a width d intervening between adjacent second recesses. A thin-film-shaped conductive bodyof width W and depth H is embedded in each of the second recesses
