1. A photoelectric conversion element comprising:
a pixel area which includes a plurality of rows and a plurality of columns;
a first filter which is provided in a first pixel constituting the pixel area and which allows passage of visible light in a first wavelength band and infrared light in a second wavelength band;
a second filter which is provided in a second pixel constituting the pixel area and which allows the passage of the visible light in the first wavelength band and the infrared light in the second wavelength band; and
a first light reduction unit which reduces the infrared light having passed through the second filter, wherein the first light reduction unit comprises a filter,
wherein a third filter which allows the passage of the visible light in the first wavelength band and the infrared light in the second wavelength band is provided in, among pixels constituting the pixel area, each pixel other than the first pixel and the second pixel, and
wherein a second light reduction unit which reduces the infrared light having passed through the third filter is provided in each pixel other than the first pixel and the second pixel constituting the pixel area, wherein the second light reduction unit comprises a filter.
