1. A light receiving element, comprising:
a plurality of pixels, each including:
a first voltage application unit to which a first voltage is applied;
a first charge detection unit provided adjacent to the first voltage application unit;
a second voltage application unit to which a second voltage different from the first voltage is applied; and
a second charge detection unit provided adjacent to the second voltage application unit; and
a trench that is arranged between the pixels adjacent to each other in a semiconductor layer.
