Abstract
To provide a photoelectric conversion element which enables an occupied area to be reduced and conversion efficiency and a dynamic range to be adjusted. The photoelectric conversion element includes: a photoelectric conversion unit configured to convert a light signal into a signal charge; a transfer gate structure which is connected to the photoelectric conversion unit and which is configured to transfer the signal charge; a charge storage region to which the signal charge is transferred by the transfer gate structure; a charge holding unit with a capacitor structure which is electrically connected to the charge storage region and which is configured to store the signal charge; and an amplifying transistor of which a control electrode is electrically connected to the charge storage region. The photoelectric conversion unit, the transfer gate structure, and the charge storage region are provided on a first substrate, the amplifying transistor is provided on a second substrate, and the first substrate and the second substrate are laminated.
