PROBLEM TO BE SOLVED: To provide an ultrafine nozzle in which the inside diameter of the tip is made into the fine one of ≤30 μm, and further, the wall thickness of the nozzle is made thin, thus the discharge of a liquid is made smooth, and which is applicable to various equipment for medical use or industrial use, and to provide a method for producing the same. SOLUTION: In the production method, a core wire 43 is subjected to special electroforming (first electroforming), and a part of the core wire 43 is exposed to thereby form a taper-shaped electroformed tube 41 with the core wire 43 attached thereto, further, second electroforming is performed to form a second electroformed tube 44, and thereafter, the core wire 43 and the first electroformed tube 41 are pulled out, thus the integrated type ultrafine nozzle using the electroformed tubes with different inside/outside diameters is formed. The tip part of the nozzle may be subjected to taper working, and the inside and outside may be plated with metal such as gold, silver and palladium. COPYRIGHT: (C)2011,JPO&INPIT
