Photoelectric conversion element, light detection device, light detection system, electronic apparatus, and moving object

The invention provides a photoelectric conversion element with enhanced function. A photoelectric conversion element includes: a semiconductor substrate; a first photoelectric conversion unit that is provided on the semiconductor substrate and detects and photoelectrically converts light in a first wavelength range; a second photoelectric conversion unit which is provided in the semiconductor substrate at a position overlapping the first photoelectric conversion unit in the thickness direction of the semiconductor substrate, and which detects and photoelectrically converts light in a second wavelength range; an optical filter that is provided between the first photoelectric conversion section and the second photoelectric conversion section in the thickness direction, and through which light in the second wavelength range passes more easily than light in the first wavelength range; and a first light shielding member surrounding the filter along a plane orthogonal to the thickness direction so as to at least pa
