A photoelectric conversion apparatus comprises: a plurality of pixels; a signal line; a holding block; an output unit; and a control unit, wherein the control unit selectively operates the holding block in a first mode or a second mode, the first mode being a mode in which a first signal is held in a first holding unit and then transferred from the first holding unit to a second holding unit via a first impedance conversion unit, and in which a second signal is held in a third holding unit and then transferred from the third holding unit to a fourth holding unit via a second impedance conversion unit, and the second mode being a mode in which the first signal is transferred to the second holding unit via the first impedance conversion unit and the second signal is transferred to the fourth holding unit via the first impedance conversion unit.
