Abstract

Disclosed is a light receiving element (1) including an on-chip lens (47), a wiring layer (42), and a semiconductor layer (41) disposed between the on-chip lens and the wiring layer. The semiconductor layer includes a photodiode (PD), a first transfer transistor (TRG1) that transfers electric charge generated in the photodiode to a first charge storage portion (FD1), a second transfer transistor (TRG2) that transfers electric charge generated in the photodiode to a second charge storage portion (FD2), and an interpixel separation portion (61) that separates the semiconductor layers of adjacent pixels from each other, for at least part of the semiconductor layer in the depth direction. The wiring layer has at least one layer including a light blocking member (63). The light blocking member is disposed to overlap with the photodiode in a plan view.
