Abstract
The present technology relates to a light receiving device and a distance measuring module capable of improving sensitivity. A light receiving device includes a pixel array unit in which pixels each having a first tap detecting charge photoelectrically converted by a photoelectric conversion unit and a second tap detecting charge photoelectrically converted by the photoelectric conversion unit are two-dimensionally arranged in a matrix. The first tap and the second tap each have a voltage application unit that applies a voltage, the pixel array unit has a groove portion formed by digging from a light incident surface side of a substrate to a predetermined depth, and the groove portion is arranged so as to overlap at least a part of the voltage application unit in plan view. The present technology can be applied to a distance measuring sensor or the like of the indirect ToF scheme, for example.
