PURPOSE:To contrive fine pulverization of a liquid efficiently, by a method wherein a plurality of nozzle orifices in a radius direction and axial direction nozzle orifices extending from said nozzle orifices to a vertical direction and supplying the liquid to the edge part of a vibrator are provided so as to be communicated with the liquid supply passage provided to the vibrator in the axial direction thereof. CONSTITUTION:For example, in a fuel nozzle 1 for a gas turbine, a liquid supply means 8 is formed in a vibrator 10 and one or more of radius direction nozzle orifices 42 extending to the radius direction of the vibrator 10 and axial direction nozzle orifices 44 extending to a vertical downward direction are respectively provided to the liquid supply passage of supply means 8 in a communicated state. Even when the flow amount of a supply liquid is reduced, the liquid is distributed to the radius direction nozzle orifices 42 from the liquid supply passage 40 and transferred to a vibrator edge part 26 along the axial direction nozzle orifices 44. At this time, because the axial direction nozzle orifices 44 are also vibrated, the liquid is well sprayed without stagnation.
