Abstract
An image sensor includes: a first readout circuit that reads out a first signal, being generated by an electric charge resulting from a photoelectric conversion, to a first signal line; a first holding circuit that holds a voltage based on an electric current from a power supply circuit; and a first electric current source that supplies the first signal line with an electric current generated by the voltage held in the first holding circuit, wherein: the first holding circuit holds the voltage based on the electric current from the power supply circuit when the first signal is not read out to the first signal line by the first readout circuit.
