1. A nozzle which is connectable to a conduit for supplying gas to a tubular body filled with granular solid matters, the nozzle comprising:
a flow path which allows the gas to flow;
one or more tip opening portions which are formed on a tip side of the flow path;
a base end opening portion which is formed on a base end side of the flow path; and
one or more side holes which are formed on the base end side from the one or more tip opening portions and allow a part of the gas flowing through the flow path to be discharged toward the base end side, wherein
the one or more tip opening portions are formed in a direction of the flow path,
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.
