A first pressure generating chamber, which is sealed by a first elastic plate mounted with a first piezoelectric element at one surface, and a second pressure generating chamber, which is sealed by a second elastic plate mounted with a second piezoelectric element at one surface are formed in a casing. The second pressure generating chamber is formed with an opening which is a discharge port. A mixture is discharged from the discharge port. A nozzle formed with an opening jets gas toward a substrate surface, and is provided in the vicinity of the discharge port of the ink head.
