Abstract
A solid-state imaging apparatus including pixels each including a photoelectric conversion element, and a light shielding layer covering the photoelectric conversion element is provided. For each of the photoelectric conversion elements, the light shielding layer includes a light shielding portion which shields a portion of incident light to the photoelectric conversion element, and an aperture which passes another portion of the incident light. The pixels include first and second pixels which have different areas on a planar view of the photoelectric conversion element. The area of the photoelectric conversion element in the first pixel is larger than the area of the photoelectric conversion element in the second pixel on the planar view. An area of the light shielding portion included in the first pixel is larger than an area of the light shielding portion included in the second pixel.
