Light-receiving element and distance measurement module

A distance measurement module comprising:

• a light-receiving element including an on-chip lens, an interconnection layer, and a semiconductor layer that is disposed between the on-chip lens and the interconnection layer, the semiconductor layer including a first voltage application unit to which a first voltage is applied, a second voltage application unit to which a second voltage different from the first voltage is applied, a first charge detection unit that is disposed at the periphery of the first voltage application unit, a second charge detection unit that is disposed at the periphery of the second voltage application unit, and a charge discharge region that is provided on an outer side of an effective pixel region;
• a light source that emits irradiation light of which brightness periodically fluctuates;
• and
• a light-emission control unit that controls an irradiation timing of the irradiation light.
