Claim 0:
1. An image-capture element, comprising:
a pixel array in which a plurality of pixels each including a photoelectric conversion element are disposed on a substrate;
a transparent layer formed on the pixel array; and
a spectroscopic element array in which a plurality of spectroscopic elements are disposed inside or on the transparent layer,
wherein each of the spectroscopic elements includes a set of microstructures composed of a plurality of microstructures formed of a material having a higher refractive index than a refractive index of the transparent layer, wherein the set of microstructures is composed of the plurality of microstructures that have a different shape in a horizontal direction with respect to the pixel array, and are disposed at constant intervals,
wherein each of the microstructures is a structure, wherein bottom and top surfaces of the structure have a shape of a rotational symmetry with a center as an axis of symmetry,
wherein at least part of light incident on the spectroscopic elements is separated into first, second, and third deflected lights that have different propagation directions according to their respective wavelengths, and the first, second, and third deflected lights are emitted from the spectroscopic elements, and enter three respective pixels disposed consecutively in one direction of the pixel array.
