In an imaging element including a polarizer, accuracy of obtained polarization information is improved. The imaging element includes a polarizer and a photoelectric conversion element, from the incident light side. A plurality of types of polarizing members is arranged on the polarizer. The plurality of types of polarizing members is polarizing members having the same internal structures, and is formed as the plurality of types of polarizing members by rotationally moving or symmetrically moving one of the polarizing members. The photoelectric conversion element converts light incident through each of the plurality of types of polarizing members into electric charges.
