Abstract
The present technology relates to a light-receiving element and a distance-measuring module. A light-receiving element includes an on-chip lens, a wiring layer, and a semiconductor layer arranged between the on-chip lens and the wiring layer, the semiconductor layer includes a first voltage application portion to which a first voltage is applied, a second voltage application portion to which a second voltage different from the first voltage is applied, a first charge detection portion arranged around the first voltage application portion, a second charge detection portion arranged around the second voltage application portion, and a pixel separation portion that separates the semiconductor layer at least up to a predetermined depth in a boundary portion of adjacent pixels, and a third voltage is applied to the pixel separation portion. The present technology can be applied to, for example, a light-receiving element that generates distance information by a ToF method.
