Abstract
In discharging a source gas from a first process gas nozzle, rectifying members including a coolant flow passage provided in a concertinaing manner therein are arranged both sides of the first process gas nozzle. Then, a coolant at a temperature higher than a liquefaction temperature of the source gas and lower than a thermal decomposition temperature of the source gas is flown through the coolant flow passage, by which the first process gas nozzle is cooled through the rectifying member.
