Beschreibung
Zusammenfassung:	An object of the invention is to improve the uniformity of the temperature distribution within the plane of a substrate. A nozzle unit according to an aspect of the invention is a unit for a liquid processing device that subjects a substrate to liquid processing using a solution. This nozzle unit comprises a gas nozzle having a discharge flow channel through which a gas is transported and a discharge port that discharges the gas flowing through the discharge flow channel toward the surface of the substrate. The discharge port is formed so as to extend in a first direction across the surface. The width of the discharge flow channel in the first direction increases with increasing proximity to the discharge port so that the gas from the discharge port is discharged in a radial pattern.
