Abstract

The invention discloses a solid-state imaging device and an electronic apparatus. A solid-state imaging device includes: a substrate; a photoelectric conversion unit that is formed on the substrate and generates signal charge in correspondence with a light amount of incident light; and a transparent electrode that is formed in an upper portion of the substrate and includes a first area formed from a nano carbon material and a second area that is brought into contact with the first area and has light transmittance higher than that of the first area. The invention provides the solid-state imaging device, in which a transparent electrode is formed, capable of solving the problems of a decrease in the transmittance of the transparent electrode and variations in the optical characteristic due to the film thickness.
