Abstract:
1. A sample analysis element comprising: a substrate; a metal film is formed on the surface of the substrate; a dielectric film is formed on the surface of the metal film; and plurality of metallic nano-body groups that includes metallic nano-bodies which are dispersed at a first pitch smaller than the wavelength of incident light and that is formed on the dielectric surface, wherein the plurality of metallic nano-body groups is arranged in one direction at a second pitch that resonates with the incident light, a region that does not include the metallic nano-body is formed between adjacent metallic nano-body groups, the metallic nano-bodies are dispersed in one direction at the first pitch smaller than the second pitch in the metallic nano-body group, and the gap between adjacent metallic nano-body groups is larger than the first pitch.
