PROBLEM TO BE SOLVED: To reduce image noise.SOLUTION: A solid-state imaging device comprises a pixel array portion in which multiple unit pixels are arranged on a semiconductor substrate, the unit pixels each including a photodiode generating and accumulating a light charge based on a quantity of received light and a charge accumulation portion accumulating the light charge. An intermediate electrode, which forms a charge accumulation portion together with an opposed upper electrode, is directly connected to an N-type semiconductor area of the semiconductor substrate. This technique is applicable to a solid-state imaging element, for example. |
