Abstract
An imaging device includes a pixel region in which a plurality of pixels and a plurality of charge-to-voltage conversion circuits are arranged in matrix. The pixels include photoelectric conversion elements that output charges in accordance with intensity of received light. The charge-to-voltage conversion circuits convert the charges output from the pixels into voltage signals. The pixel region includes an isolated region including isolated shaded pixels covered with a first shading metal of the same layer as a layer of wiring metals of the charge-to-voltage conversion circuits, and an isolated pixel that is not covered with the metal. All the pixels surrounding the isolated pixel in the isolated region are the isolated shaded pixels.
