The present invention addresses the problem of providing a method for forming an electrode pattern, an organic thin-film transistor, and an electrode material for an organic semiconductor device with which it is possible to form an excellent electrode pattern. This electrode material for an organic semiconductor device is an electrode material that contains inorganic nanoparticles, an organic π-conjugated ligand, and water, wherein the organic π-conjugated ligand has at least one hydrophilic substituent, and the electrode material for an organic semiconductor device contains 0.0005-15% by mass of a fluorine-based surfactant and also contains a surface tension regulator having a permittivity of 20-30. |
