To provide an electrode for realizing an n-type organic transistor having high mobility and an organic semiconductor device using electrons as carriers and having high performance.
The problem is solved by the organic semiconductor device. The organic semiconductor device has at least an organic semiconductor layer 40. The organic semiconductor device further has at least electrodes 2 and 3 forming a conductive charge transfer complex, by combining an electron donative molecular material with an electron acceptable molecular material having an ionizing energy the same as or similar to a molecular material constituting an organic semiconductor in the electrodes or parts of the electrodes on the sides brought into contact with the organic semiconductor, for improving the injection efficiency of electrons to the organic semiconductor as the electrodes constituting electrical contacts with the organic semiconductor layer.
