An object is to provide a Raman scattering light enhancing device that provides a sufficiently high Raman scattering light enhancing effect and produces a highly sensitive Raman signal even by using an excitation light source having a low energy density. This Raman scattering light enhancing device includes a substrate, a high reflection layer that is formed on the substrate, a dielectric layer that is formed on the high reflection layer, and an enhanced electromagnetic field formation layer that is formed on the dielectric layer and includes a large number of fine silver particles. A gold film is formed on surfaces of the fine silver particles constituting the enhanced electromagnetic field formation layer.
