Abstract
An imaging device according to an example of the invention comprises a first photoelectric conversion unit which is formed at an imaging area of a substrate, a second photoelectric conversion unit for black reference observation which is formed at an optical black area between the imaging area of the substrate and a peripheral circuit area where a peripheral circuit is formed, an insulating film which is formed on the imaging area and the optical black area of the substrate, and a shielding unit which is formed by connecting a contact and a interconnect in an accumulating direction of the insulating film from the substrate surface to the insulating film surface.
