Abstract

Provided is a highly-sensitive color image-capture element and an image capture device that can be simply manufactured, have little polarization dependency, and have micro-spectroscopic elements capable of separating incident light into three wavelength ranges integrated facing a two-dimensional pixel array. An image capture elementhas a transparent layerhaving a low refractive index made of SiOor the like and a plurality of micro-lenseslaminated on a two-dimensional pixel array in which pixelseach including a photoelectric conversion element are disposed in an array. Inside the transparent layerhaving the low refractive index, micro-spectroscopic elementscomposed of a plurality of microstructures having constant thickness (length in a direction perpendicular to the two-dimensional pixel array) formed of a material such as SiN having a higher refractive index than that of the transparent layeris embedded.
