摘要： A highly functional photoelectric conversion element is provided. The photoelectric conversion element includes: a semiconductor substrate; a first photoelectric converter that is provided on the semiconductor substrate, and detects light in a first wavelength range and photoelectrically converts the light; a second photoelectric converter that is provided at a position overlapping the first photoelectric converter in a thickness direction of the semiconductor substrate in the semiconductor substrate, and detects light in a second wavelength range and photoelectrically converts the light; an optical filter that is sandwiched between the first photoelectric converter and the second photoelectric converter in the thickness direction, and through which the light in the second wavelength range passes more easily than the light in the first wavelength range; and a first light-shielding member that surrounds the optical filter along a plane orthogonal to the thickness direction to at least partially overlap the optical filter in a plane direction along the plane, and shields at least the light in the second wavelength range.
