LIGHT-RECEIVING ELEMENT

[Problem] Provided is a light-receiving element capable of suppressing variations in electrical characteristics even when there is a temperature gradient.[Solution] A light-receiving element of the present disclosure includes: a pixel region in which a plurality of photodiodes is arranged; a readout circuit region including a plurality of readout circuits provided corresponding to the plurality of photodiodes, respectively; a first thermometer provided corresponding to a first circuit region of the readout circuit region; a second thermometer provided corresponding to a second circuit region of the readout circuit region; a first control circuit that applies a first voltage corresponding to a temperature of the first circuit region measured by the first thermometer to the photodiode corresponding to the readout circuit in the first circuit region; and a second control circuit that applies a second voltage corresponding to a temperature of the second circuit region measured by the second thermometer to the photodiode corresponding to the readout circuit in the second circuit region.
