Imaging device with inter-pixel and in-pixel separation sections

Abstract

An imaging device according to an embodiment of the present disclosure includes: a semiconductor substrate in which a plurality of pixels is arranged in a matrix, the semiconductor substrate including a plurality of photoelectric conversion sections that each generate electric charge corresponding to a light receiving amount by photoelectric conversion for each of the pixels; an inter-pixel separation section between the pixels adjacent to each other, electrically and optically separating the adjacent pixels from each other, and having a first refractive index; and an in-pixel separation section between the photoelectric conversion sections adjacent to each other inside each of the pixels, electrically separating the adjacent photoelectric conversion sections, and having a second refractive index, a difference between the second refractive index and a refractive index of the semiconductor substrate being smaller than a difference between the first refractive index and the refractive index of the semiconductor substrate.
