Abstract
The present technology relates to a light-receiving element and a distance measurement module. A light-receiving element includes: a first voltage application unit to which a voltage is applied; a first charge detection unit that is disposed at a periphery of the first voltage application unit; a second voltage application unit to which a voltage is applied; a second charge detection unit that is disposed at a periphery of the second voltage application unit; a third voltage application unit to which a first voltage is applied; and a voltage control unit that applies a second voltage to one of the first voltage application unit and the second a voltage application unit and causes the other to be in a floating state, the second voltage being different from the first voltage. The present technology is applicable to a light-receiving element.
