摘要： Provided are an optical element and an optical device using the optical element to which a manufacturing process for manufacturing a wire-grid structure can be basically applied, and besides, in which a higher polarization contrast ratio than that of a wire-grid element can be obtained. A wobbled wire element in an embodiment has a feature that a periodic structure having a period equal to or larger than a wavelength of an incident light wave is formed in a y direction. In this manner, in a wobbled wire element in a first embodiment, a polarization contrast ratio can be significantly improved.

A wire-grid in which a plurality of line-shaped wires P10 made of Al and extending in a y direction are arranged at spaces S in an x direction is provided in the wire-grid region 1A of the substrate 1S, and a pattern (repetitive pattern) in which a plurality of protruding portions P20 made of Al are arranged is provided in the peripheral region 2A. This pattern is, for example, a checkerboard pattern. According to the above-mentioned configuration, the plurality of wires P10 can be arranged so that their respective ends are spaced apart from an end of the substrate 1S, so that the wires P10 can be prevented from being deformed and nicked. Also, by the plurality of protruding portions P20 in the peripheral region 2A, it is possible to prevent water from entering the wire-grid region 1A.
