Abstract
The present technology relates to a light-receiving element and a distance-measuring module for enabling improvement of characteristics. 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 near the first voltage application portion, and a second charge detection portion arranged near the second voltage application portion, and each of the first voltage application portion and the second voltage application portion is covered with an insulating film in the semiconductor layer. The present technology can be applied to, for example, a light-receiving element that generates distance information by a ToF method.
