1. An imaging device comprising:
a first substrate;
a second substrate;
a plurality of photoelectric conversion units disposed in the first substrate within an area; and
a memory configured to hold a digital signal having a signal value corresponding to a signal generated by at least one of the plurality of photoelectric conversion units,
wherein a first light shielding member is disposed between the first substrate and the second substrate,
wherein at least a part of the memory is located within a first projection region defined by vertically projecting the first shielding member onto the second substrate side, and
wherein a second projection region defined by vertically projecting at least a part of the area onto the second substrate side, overlaps with the first projection region.
