Abstract
A device includes a plurality of photoelectric conversion regions, an interlayer insulating film arranged on the plurality of photoelectric conversion regions, a protective insulating film that is arranged in contact with the interlayer insulating film and has a refractive index different from that of the interlayer insulating film, recesses arranged in a light-receiving surface of each of the plurality of photoelectric conversion regions, and embedded regions embedded in the recesses. When a wavelength of incident light to each of the plurality of photoelectric conversion regions is denoted by λ and a refractive index of the embedded regions is denoted by n, a depth d of the recesses is represented by an expression d≧λ/4n.
