Abstract
The present invention provides a solid-state imaging device including an optical element that efficiently condenses even a wide-angle incident light and has a color separation function. The solid-state imaging device includes pixels, and in the device each pixel includes: a light receiving element; and an optical element, whose surface at least, is made of metal, the optical element has: an aperture; and convex parts which are arranged cyclically, and a distance between adjacent convex parts and a width of each convex part range from 0 to 1 wavelength of light to be condensed.
