Abstract:
There is provided an image pickup apparatus including a pixel including a photoelectric conversion element and an amplification element for amplifying and outputting a signal generated at the photoelectric conversion element, a load transistor for controlling an electric current flowing at the amplification element, and a potential control element for suppressing potential fluctuation in a first main electrode region of the load transistor which is an output side of the amplification element.
