摘要:
A highly functional photoelectric conversion element is provided. The photoelectric conversion element includes: a first photoelectric converter that detects light in a first wavelength range and photoelectrically converts the light; a second photoelectric converter that detects light in a second wavelength range and photoelectrically converts the light to obtain distance information of a subject; and an optical filter that is disposed between the first photoelectric converter and the second photoelectric converter, and allows the light in the second wavelength range to pass therethrough more easily than the light in the first wavelength range. The first photoelectric converter includes a stacked structure and an electric charge accumulation electrode. The stacked structure includes a first electrode, a first photoelectric conversion layer, and a second electrode that are stacked in order, and the electric charge accumulation electrode is disposed to be separated from the first electrode and be opposed to the first photoelectric conversion layer with an insulating layer interposed therebetween.
