Abstract
To prevent leakage of incident light from pixels around a pixel region () of a light receiving element. A light receiving element includes a pixel region and an adjacent pixel (). In the pixel region, a plurality of pixels () is arranged, the plurality of pixels including a photodiode formed in a semiconductor substrate () in which a charge generated by photoelectric conversion of incident light is multiplied with a high reverse bias voltage, an on-chip lens () that focuses the incident light on the photodiode, and a wiring region () having a wiring layer () connected to the photodiode and an insulating layer () that insulates the wiring layer. The adjacent pixel is arranged adjacent to the pixel region and includes the photodiode, an on-chip lens () having a curvature different from a curvature of the on-chip lens, and the wiring region.
