[Problem] To provide a flow path tube that prompts gas/liquid stirring of fluids flowing through a tube channel, enables adjustment of the flow rate, and furthermore suppresses passage of foreign substances.[Solution means] A flow path tube 1 is configured by inserting and disposing within a tube channel 12 of a flow path tube body 10 at least one or more porous materials 20 having a continuous void structure and a necessary length/a necessary diametrical dimension. Moreover, at least one or more ejection holes 18 are formed at given positions in the flow path tube body 10 or in the porous material 20 to form a jet nozzle tube 14 using the flow path tube 1. Furthermore, a valve body 26 is attached to the base end 10c of the flow path tube body 10 to form an aerosol valve tube 16 using the flow path tube 1.
