Claim 2:
3. 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, 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, wherein the pixel array is disposed at a position to receive lights that are spectralized by the plurality of spectroscopic elements to different propagation directions according to their respective wavelengths, and
wherein a part of the plurality of spectroscopic elements of the set of microstructures has a shape different from that of remains of the plurality of spectroscopic elements of the set of microstructures.
