A protection circuit and a photoelectric conversion device are provided, each of which includes a first wiring, a second wiring, a first switch, a second switch, a capacitor, and a comparing circuit configured to generate a signal corresponding to a potential of the first wiring and a potential of the second wiring, and supply the signal to the first switch and the second switch. The first wiring is electrically connected to a first terminal of the first switch, and the second wiring is electrically connected to a first terminal of the second switch. A second terminal of the first switch is electrically connected to a first electrode of the capacitor, and a second terminal of the second switch is electrically connected to a second electrode of the capacitor. |
