Abstract
A device for Raman spectroscopy comprises a fine structure body provided with an array structure region, in which a plurality of recess areas having approximately identical shapes, as viewed from above, are arrayed regularly at approximately identical pitches. A surface of the fine structure body on the side of the array structure region acts as a light scattering surface. The fine structure body may be constituted of an un-anodized part of a metal body to be subjected to anodic oxidation processing, the un-anodized part remaining after a processing, wherein the anodic oxidation processing is performed on the metal body, a part of the metal body being thereby converted into a metal oxide layer, and wherein the metal oxide layer is removed from the metal body, has been performed.
