Abstract

An organic photoelectric conversion element includes an anode, a cathode, and a photoelectric conversion portion between the anode and the cathode. The photoelectric conversion portion includes a first organic compound layer containing an organic compound. Also, a second organic compound layer is disposed between the cathode and the photoelectric conversion portion. The second organic compound layer contains an organic compound having an ionization potential of 5.1 eV or less and a band gap of 2.5 eV or more.
