PURPOSE:To enable to obtain an extremely minute liquid-jetting nozzle extremely easily, by a method wherein three round rods are fixed in the condition of making contact with each other, and a liquid is jetted from a hollow part defined by the three round rods. CONSTITUTION:Three round rods 1 are bondled in the condition of making contact with each other, and are fixed in situ by filling the recessed parts formed at the outside parts of the rods 1 with an adhesive 2 based on an epoxy resin or the like, whereby a minute hollow part 3 is defined at a central part. The hollow part 3 is utilized as a passage for a liquid, and the liquid is jetted from an outlet of the passage. The smoothness of the inside surface of the hollow part 3 can be easily enhanced by finishing the outside surfaces of the rods 1 to be smooth by polishing before fixing them, or by subjecting the outside surfaces to a plating treatment. |
