Abstract

A light-receiving element includes 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 includes 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. For example, the present technology is applicable to a light-receiving element that generates distance information in a ToF method, or the like.
