PROBLEM TO BE SOLVED: To inexpensively provide a vertical organic transistor that is improved in current density and operational speed and can be mass-produced with high reproducibility. SOLUTION: This vertical organic transistor 10 has a first electrode 2, a first organic semiconductor layer 4, a comb-shaped or meshed second electrode 5, a second organic semiconductor layer 6, and a third electrode 7 successively formed on a substrate 1 in this order. This transistor 10 also has an electric charge injection layer and/or an electric charge transfer layer 3 between the first electrode 2 and the first organic semiconductor layer 4. The electric charge injection layer is constituted of an organic semiconductor material such as the m-MTDATA, CuPc, PEDOT, PSS, etc., each having an electric charge injecting property. In addition, the electric charge transfer layer 3 is constituted of the other organic semiconductor material such as theα-NPD, TPD, Spiro-TAD, etc., each having an electric charge transferring property.
