A solid-state imaging device includes a photoelectric converter (30) including a plurality of light receiving elements arranged along one direction in correspondence with each color of received light, each light receiving element generating an electric charge corresponding to an amount of received light, an electric charge storage unit (40) including a plurality of capacitors storing the electric charges generated by the respective light receiving elements, and a signal processing unit (28) configured to process each of the electric charges stored by the plurality of capacitors as a signal. The electric charge storage unit (40) is disposed so as to oppose the signal processing unit (28) across the photoelectric converter (30).
