Abstract: An organic photoelectric conversion device includes first and second organic photoelectric conversion elements which convert light into electrical energy. The first and second organic photoelectric conversion elements are disposed to be stacked in this order along an incident direction of the light. The first organic photoelectric conversion element includes a first element main body including a first substrate, first and second transparent electrodes, and an organic photoelectric conversion unit having sensitivity in a first wavelength band of the light, and a first protective film that covers the first element main body. The second organic photoelectric conversion element includes a second element main body including a second substrate, a third transparent electrode, an electrode, and an organic photoelectric conversion unit having sensitivity in a second wavelength band of the light, and a second protective film that covers the second element main body.

Abstract: A photoelectric tube includes a housing including a light transmitting portion, an electron emitting portion held by a recess provided in the housing, the electron emitting portion including a concave photoelectric surface facing a light transmitting portion side inside the housing, and an electron capturing portion disposed between the light transmitting portion and the photoelectric surface inside the housing. At least a part of the electron capturing portion is located inside a region on an inside of the photoelectric surface.
