A photoelectric conversion apparatus includes a photoelectric conversion element, an amplification transistor having a gate electrically connected to the output terminal of the photoelectric conversion element, a switching element having one terminal electrically connected to an electrical path which connects the output terminal of the photoelectric conversion element to the gate of the amplification transistor, and the other terminal electrically connected to a node capable of providing a voltage lower than the power supply voltage with the other terminal; and a control unit for controlling the voltage provided by the node and ON/OFF state of the switching element, wherein the control unit causes the node to provide the voltage lower than the power supply voltage with the other terminal of the switching element and turns on the switching element during a period in which a signal generated by photoelectric conversion of the photoelectric conversion element is not used.
