Title: Sample analysis element and detecting device

Abstract: A plurality of metallic nano-body groups that includes metallic nano-bodies which are dispersed on a dielectric surface at a first pitch smaller than the wavelength of incident light is arranged in one direction at a second pitch that resonates with the incident light. Localized surface plasmon resonance occurs in the metallic nano-body by the action of the incident light. Propagating surface plasmon resonance occurs by the action of the second pitch. The propagating surface plasmon resonance is combined with the localized surface plasmon resonance. A so-called hybrid mode is established.
