Abstract
An image pickup apparatus includes a plurality of pixels each including a photoelectric conversion unit, an amplification element configured to amplify a signal based on a signal charge generated in the photoelectric conversion unit, and a first signal holding unit and a second signal holding unit located at a stage following the first signal holding unit and arranged on an electric path between the photoelectric conversion unit and an input node of the amplification element, in which a coverage by a light-shielding member of the first signal holding unit is lower than a coverage by a light-shielding member of the second signal holding unit.
