Abstract
To reduce occurrence of crosstalk in a back-illuminated image capturing element. An image capturing element includes: a pixel including a photoelectric conversion section, a pixel circuit, and a wiring layer; and a polarization section. The photoelectric conversion section is formed on a semiconductor substrate and performs photoelectric conversion based on incident light. The pixel circuit generates an image signal according to a charge generated by the photoelectric conversion. The wiring layer is arranged on a surface of the semiconductor substrate and is configured to transmit any one of the image signal or a signal applied to the pixel circuit, the surface being different from a surface of the semiconductor substrate on which the incident light is incident. The polarization section is arranged between the semiconductor substrate and the wiring layer, and allows transmission of light in a specific polarization direction among incident light transmitted through the photoelectric conversion section.
