PROBLEM TO BE SOLVED: To provide a sample analysis element capable of connecting localized surface plasmon resonance with propagating surface plasmon resonance while the surface density of a hot spot is increased.SOLUTION: A sample analysis element 11 includes a plurality of metal nano rows 16. Each of the metal nano rows 16 includes a plurality of metal nano bodies 15 arrayed in a line at a first pitch SP smaller than a wavelength of incident light on a dielectric surface. The metal nano rows 16 are arrayed in parallel to each other at a second pitch LP larger than the first pitch SP. |
