摘要：
In a photoelectric conversion apparatus, an error can occur due to a voltage drop through a MOS transistor. In the photoelectric conversion apparatus, to reduce the error, a circuit block disposed between a unit pixel and an output line includes a differential amplifier circuit and a switch that is disposed in a feedback path of the differential amplifier circuit.
