Abstract

An image sensor of the present disclosure includes a two-dimensional pixel array in which a plurality of pixels including photoelectric conversion elements are arranged in the form of an array on a substrate, a transparent layer formed on the two-dimensional pixel array, and a two-dimensional spectroscopic element array in which a plurality of spectroscopic elements are arranged in the form of an array inside or on the transparent layer. Each spectroscopic element includes a plurality of microstructures made of a material having a higher refractive index than a refractive index of the transparent layer. The plurality of microstructures have a microstructure pattern. Each of the spectroscopic elements splits incident light into first to fourth deflected lights, which have different transmission directions, according to the wavelength region. A first to fourth pixels, which are adjacent to each other and are located directly below each of the spectroscopic elements, respectively detect the first to fourth deflected lights.
