Abstract
Pixel formation in an imaging element configured to detect image plane phase difference is simplified. The imaging element includes an on-chip lens, a plurality of photoelectric conversion portions, and a plurality of waveguides. The on-chip lens concentrates incident light on a pixel and is placed on each pixel so as to be shifted from a center of the pixel according to an incident angle of the incident light. The plurality of photoelectric conversion portions is arranged in the pixel and performs photoelectric conversion according to the incident light. The plurality of waveguides is arranged for the plurality of respective photoelectric conversion portion in the pixel. The plurality of waveguides guide the incident light concentrated so that the incident light enters each of the plurality of photoelectric conversion portion, and are formed into shapes dissimilar to each other based on the shift of the on-chip lens.
