A1

[Problem] To provide: a nozzle that can achieve an improvement in the work efficiency and work accuracy of work for extracting solid matter from a pipe body; a device for extracting solid matter; a system for extracting solid matter; and a method for extracting solid matter. [Solution] A nozzle 100 has: a flow path 140 through which gas flows; a tip opening part 111 that is formed on a tip side of the flow path 140; a base end opening part 121 that is formed on a base end side of the flow path 140; and a side hole that is formed closer to the base end side than the tip opening part 111 and discharges, toward the base end side, a portion of the gas flowing through the flow path 140, wherein one or more tip opening parts are formed toward the flow path direction, one or more side holes are formed along a circumferential direction of the flow path, and when the gas is supplied from the base end opening part, a ratio (Q1a/Q1b) of a gas flow rate (Q1a) discharged from the one or more tip opening parts to a gas flow rate (Q1b) discharged from the one or more side holes is 0.05 to 0.7.
