This surface-enhanced Raman scattering element is characterized by being provided with: a substrate having a primary surface; a molded layer which includes a support part formed on the primary surface of the substrate and extending along the primary surface, and a microstructure part formed on the support part; a frame part which is formed on the primary surface so as to surround the support part and the microstructure part along the primary surface of the substrate; and a conductor layer which is formed on at least the microstructure part and which configures an optical functional part which generates surface-enhanced Raman scattering, wherein the microstructure part is formed integrally with the support part.
