PROBLEM TO BE SOLVED: To provide a method for efficiently manufacturing a nano-hole structure which is applicable for various fields, such as a magnetic recording medium, a DNA chip and a catalyst base plate, and further to provide a method for manufacturing a very high quality magnetic recording medium, etc., which can perform high density recording and high speed recording without increasing a writing current of a magnetic head, and has a large capacity, and is excellent in the over-writing property, and has a uniform characteristic, and does not cause the problems such as cross-reading and cross-writing. SOLUTION: The method for manufacturing the nano-hole structure includes a step of smoothing the surface of a metallic layer after forming it on a base material, a step of forming origins for forming the nano-holes on the smoothed metallic layer, and a step of forming a porous layer having a plurality of nano-holes formed in the direction nearly perpendicular to the base material.
