PROBLEM TO BE SOLVED: To provide an organic photoelectric conversion material having a high molar absorption coefficient in a red light region, and to provide a photoelectric conversion element capable of photoelectric conversion in all visible light regions with high photoelectric conversion efficiency through using the material in a photoelectric conversion film.SOLUTION: A photoelectric conversion element includes: an electron capturing electrode 5; a hole capturing electrode 4; and at least one organic compound layer 1 arranged between the electron capturing electrode 5 and the hole capturing electrode 4. In the organic compound layer 1, a vinyl group is bonded directly to an amino group, and the amino group includes a hydrocarbon aromatic ring group or a heteroaromatic ring group as a substituent group. The photoelectric conversion element uses an organic compound of a structure having an electron-withdrawing substituent group (for instance, organic compounds 1 and 2) as a photoelectric conversion material.SELECTED DRAWING: Figure 1 【課題】赤色光領域におけるモル吸光係数の高い有機光電変換材料を提供し、該材料を光電変換膜に用いることで、可視光全領域における光電変換が可能で、光電変換効率が高い光電変換素子の提供。【解決手段】電子捕集電極５と、正孔捕集電極４と、電子捕集電極５と正孔捕集電極４との間に配置される少なくとも一層の有機化合物層１を有する光電変換素子において、該有機化合物層１において、アミノ基に直接ビニル基が結合し、該アミノ基が置換基として炭化水素芳香環基又は複素芳香環基を備え、さらに、電子吸引性の置換基を備えた構造の有機化合物（例えば、有機化合物１及び２）を光電変換材料として用いる光電変換素子。【選択図】図１
