To provide a nozzle and a method for producing the nozzle.SOLUTION: A method for producing the nozzle includes processes of: (a) supplying a first material that can receive multi-photon reaction; (b) forming a first microstructured pattern in the first material by using a multi-photon process; (c) duplicating the first microstructured pattern in a second material to produce a first mold having a second microstructured pattern; (d) duplicating the second microstructured pattern in a third material to produce a second mold having a third microstructured pattern with a plurality of microstructures in the third material; (e) planarizing the third microstructured pattern of the second mold in a layer of a fourth material and in the layer, exposing a top of each of the microstructures constituting the third microstructured pattern; and (f) removing the third material to obtain a nozzle having a plurality of holes in the fourth material, in which the holes correspond to the plurality of microstructures constituting the third microstructured pattern.SELECTED DRAWING: Figure 2 【課題】ノズル及びそのノズルを作製する方法を提供する。【解決手段】（ａ）多光子反応を受けることが可能な第１の材料を供給する工程、（ｂ）多光子過程を用いて第１の材料内に第１の微細構造化パターンを形成する工程、（ｃ）第２の材料内に第１の微細構造化パターンを複製して、第２の微細構造化パターンを有する第１の型を作製する工程、（ｄ）第３の材料内に第２の微細構造化パターンを複製して、第３の材料内の複数の微細構造を有する第３の微細構造化パターンを有する第２の型を作製する工程、（ｅ）第４の材料の層で第２の型の第３の微細構造化パターンを平坦化する工程で、その層は第３の微細構造化パターンをなす各微細構造の頂部を露出させる工程、（ｆ）第３の材料を除去する工程であって、第４の材料内の複数の穴を有するノズルが得られ、それらの穴は第３の微細構造化パターンをなす複数の微細構造に対応する工程とを含む。【選択図】図２
