PROBLEM TO BE SOLVED: To provide a more efficient fuel injector in accordance with an environmental standard.SOLUTION: A method for producing a nozzle includes the steps of: (a) supplying a first material that can receive multiphoton reaction; (b) forming a first microstructured pattern in the first material by using a multiphoton process; (c) replicating the first microstructured pattern in a second material different from the first material and producing a first mold having a second microstructured pattern in the second material; (d) replicating the second microstructured pattern in a third material different from the first and second materials and producing a second mold having a third microstructured pattern including a plurality of microstructures in the third material; (e) planarizing the third microstructured pattern in the second mold with a layer of a fourth material different from the third material, where the layer exposes a top portion of each of the plurality of the microstructures forming the third microstructured pattern; and (f) removing the third material.SELECTED DRAWING: Figure 2 【課題】環境基準のため、より効率的な燃料噴射器を提供する。【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と、（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と、（ｃ）第１の材料とは異なる第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の材料内の第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と、（ｄ）第１及び第２の材料とは異なる第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と、（ｅ）第３の材料とは異なる第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あって、その層は、第３の微細構造化パターンをなす複数の微細構造の各微細構造の頂部を露出させる、工程と、（ｆ）第３の材料を除去する工程からなる、ノズルを製作する方法。【選択図】図２
