PROBLEM TO BE SOLVED: To provide a microstructure which has a high degree of regularization, and in which the center-to-center distance between micropores is wide and film thickness reaches≥50μm, and to provide a method for producing the same. SOLUTION: Disclosed is a microstructure comprising an anodized film of aluminum or an aluminum alloy, wherein the degree of regularization of a plurality of micropores on the bottom surface is 70% or more, the center-to-center distance between the micropores is 600 nm or more, and the length of each micropore in the axial direction is 50μm or more. Also disclosed is a method for producing the microstructure. COPYRIGHT: (C)2011,JPO&INPIT
