A method for forming an organic semiconductor film having a high carrier mobility is provided by having an average volatilization rate of a solvent within a prescribed range during a step of drying, at the time of applying a coating solution, which includes an organic semiconductor material and a non-halogen solvent, on a substrate. In such forming method, characteristic fluctuation in repeated use of the organic semiconductor film is suppressed, and an organic thin film transistor having an excellent film forming characteristic even on an insulator with reduced gate voltage threshold can be obtained.
