A photoelectric conversion element is provided which includes a first electrode, an electron transport layer, a photoelectric conversion layer, a hole transport layer, a second electrode, and an insulating layer each overlying a substrate. The first electrode includes a transparent conductive thin-film layer (a), a metal thin-film layer, and a transparent conductive thin-film layer (b). The electron transport layer contains metal oxide particles. The photoelectric conversion layer contains two or more organic materials. The photoelectric conversion element satisfies the following relation: 7.0 ≦ T/D ≦ 40.0 where D represents an average particle diameter of the metal oxide particles and T represents an average thickness of the photoelectric conversion layer. |
