PROBLEM TO BE SOLVED: To provide apatite fine structure having homogeneity of high precision and desired shape and to provide a method for easily forming a desired apatite pattern. SOLUTION: The fine structure containing a part where an apatite layer is stacked on a base material and a part where the apatite layer is not stacked on the base material and/or their combination is provided. Further a method for forming the apatite layer having the desired pattern or structure on a base material surface contains (a) a process in which a region where the apatite layer is not to be formed is covered with a covering material on at least one surface of the base material (b) a process in which the apatite layer is formed (c) a process in which the covering material is removed.
