Abstract
The present invention relates to a process for producing a structure having holes at prescribed positions. The structure is produced through steps of (A) providing an impressing member having protrusions, and a substrate, (B) forming a layer, on the substrate, from a material having a less strength than the impressing member, (C) forming depressions by impressing the impressing member on the layer corresponding to protrusions of the impressing member, (D) etching the layer to bare at least a part of the surface of the substrate, and (E) anodizing the substrate to form holes on the substrate.
