Abstract

A solid-state imaging device includes a light blocking layer formed in an active pixel region of a pixel region on a light incident side so as to surround a photoelectric conversion unit of each pixel and formed in an extending manner to an optical black region, a concave portion formed so as to be surrounded by the light blocking layer in a region corresponding to the photoelectric conversion unit, a first refractive index layer formed on surfaces of the light blocking layer and the concave portion and having a relatively low refractive index, a second refractive index layer formed on the first refractive index layer so as to be buried in the concave portion and having a relatively high refractive index, and an anti-flare layer formed on the first refractive index layer in the optical black region.
