A multilayer film having two kinds of films of different refractive indexes alternately stacked on each other on a substrate composed of an optical element is formed in a plurality of parallel lines, and the adjacent lines of the multilayer film are connected to each other by means of a connecting multilayer film to reinforce them. This makes it possible to provide a highly reliable optical component which shows good polarization characteristic even for a visible light of a wavelength of 400 to 700 nm and in which even when designed to have a high aspect ratio, the linear multilayer film will not fall down. There is also provided a manufacturing method that enables a fine recess/protrusion shape to be surely formed using an inexpensive manufacturing apparatus without use of any organic solvent. <IMAGE> |
