PROBLEM TO BE SOLVED: To provide a structure in which perceptibility is excellent to a lens of a tip of an endoscope.SOLUTION: A structure 1 comprises that an uneven structure layer 4 is arranged in at least a part of a surface of a substrate 2 composing a surface of a lens of an endoscope tip, and is that the uneven structure layer 4 has a surface fine uneven structure that is formed by deposition of a polymer particle 3, and the polymer particle 3 is immobilized to the substrate 2 by fusion. The structure 1 further has an antifouling property layer 5 that includes a fluorine-containing compound on a surface side of the uneven structure layer 4.COPYRIGHT: (C)2015,JPO&INPIT【課題】内視鏡の先端部のレンズに対して、視認性に優れる構造体を提供する。【解決手段】内視鏡先端部のレンズの表面を構成する基材2の表面の少なくとも一部に凹凸構造層4を配置してなる構造体1であって、凹凸構造層4は、ポリマー粒子3の堆積により形成される表面微細凹凸構造を有し、ポリマー粒子3は基材2に融着により固定化される。前記凹凸構造層4の表面側にフッ素含有化合物を含有する防汚性層5を更に有する構造体1。【選択図】図1
