the one or more side holes are formed along a circumferential direction of the flow path,
when the gas is supplied from the base end opening portion, a ratio (Q1a/Q1b) of a flow rate (Q1a) of the gas discharged from the one or more tip opening portions and a flow rate (Q1b) of the gas discharged from the one or more side holes is 0.05 to 0.7, and
each diameter of the one or more side holes is 1.0 to 2.4 mm.
