| Zusammenfassung: | To provide an electronic element that comprises a charge transport layer achieving both high conductivity and high transparency in a visible light region while containing a metal oxide.SOLUTION: An electronic element 1 comprises an anode 50, a cathode 20, a charge transport layer 30 located between the anode 50 and the cathode 20. The charge transport layer 30 contains a metal oxide, and a compound having reducibility higher than that of the metal oxide. A rate of content of the compound having the reducibility higher than that of the metal oxide is 10 pts.mass or less per 100 pts.mass of the metal oxide.SELECTED DRAWING: Figure 8
