The deterioration of the image quality of an imaging element is to be prevented. The imaging element includes an on-chip lens, a photoelectric conversion unit, and a plurality of in-layer lenses. The on-chip lens collects incident light from a subject. The photoelectric conversion unit performs photoelectric conversion on the collected incident light. The plurality of in-layer lenses that is arranged between the on-chip lens and the photoelectric conversion unit and that is configured to further collect the incident light that has passed through the on-chip lens. Furthermore, the plurality of in-layer lenses allows the incident light that has passed through any one of the plurality of in-layer lenses to be incident on the photoelectric conversion unit.
