PROBLEM TO BE SOLVED: To provide a light weighted and low costed nozzle by a method wherein cutting work is decreased, molding and assembling can be easily and in a short time carried out, and a dispersion of a jet amount of spray liquid per each nozzle is eliminated. SOLUTION: A nozzle comprises a synthetic resin-made body 5 wherein an inner hollow partαis formed, and a liquid jet metal tool 8 for jetting spray liquid having flowed into the inner hollow partαis buried; and a nozzle chip 6 wherein an inletβ1 is positioned on an end face of a large diameter part 6a fitted in the inner hollow partα, an outletβ2 on a peripheral wall 6b' of a small diameter part 6b continuously connected to the large diameter part 6a, a spray liquid introducing holeβto which the outletβ2 is positioned, and vortex generating grooves 6c, 6c for gathering a vortex in the spray liquid flowing into the liquid jet metal tool 8 on an end face 6b" of the small diameter part 6b, are formed.
