Abstract:
In a photoelectric conversion apparatus having a plurality of unit cells, wherein each of the unit cells has a photoelectric conversion element, a transfer transistor and a floating diffusion region, a light shielding portion arranged on an upper portion of the floating diffusion region is included. The respective light shielding portions are separated from one another, and are in a floating state without being electrically connected to the floating diffusion region.
