An organic thin film having excellent film quality is formed. A vapor generator of the present invention has an evaporation chamber, a dispense head and a tank. A vapor deposition material is in the liquid state, stored in the tank, and fed to the dispense head from the tank. The dispense head dispenses the vapor deposition material fed inside thereof from a dispense orifice and disposes the vapor deposition material on a heating member inside the evaporation chamber. The dispense head accurately feeds the vapor deposition material by a required amount. Because only the required amount of the vapor deposition material is heated, an organic thin film excellent in film quality is formed without deterioration.
