1. A thin structure containing numerous conical sections on its surface, while: conical sections have a mesostructure; the mesostructure contains a structure having mesopores. 2. The fine structure of claim 1, wherein when the length of the bottom line of the conical sections is indicated by D and the height of the conical sections is indicated by H, the H / D ratio is 1/2 or more. 3. The fine structure of claim 1, wherein the conical sections are 50 nm or more high. The fine structure according to claim 1, in which the average interval p between the vertices of the conical sections adjacent to each other is 400 nm or less. The fine structure according to claim 1, in which, when the average interval between the vertices of the conical sections adjacent to each other is denoted by p and the standard deviation of the distribution of the intervals between the vertices is denoted by σ, the following expression is satisfied 1: 0.1 σ / p 0, 5 (Expression 1) .6. The fine structure according to claim 1, in which the inner space of the mesopores is empty. The fine structure of claim 1, wherein one of the organic material and inorganic material is present in the mesopores. The fine structure of claim 7, wherein the inorganic material is present in the mesopores, and wherein the inorganic material contains any of silicon oxide, zirconium oxide, and titanium oxide. The fine structure of claim 1, wherein the mesopores are cylindrical. 10. The fine structure of claim 1, wherein the mesopores are periodically located, and upon X-ray diffraction analysis, the structure showed a diffraction peak corresponding to a structural period of 1.0 nm or greater.
