Abstract: A SERS element comprises a substrate; a fine structure part formed on a front face of the substrate and having a plurality of pillars; and a conductor layer formed on the fine structure part and constituting an optical function part for generating surface-enhanced Raman scattering. The conductor layer has a base part formed along the front face of the substrate and a plurality of protrusions protruding from the base part at respective positions corresponding to the pillars. The base part and the protrusions form a plurality of gaps in the conductor layer, each of the gaps having an interstice gradually decreasing in the projecting direction of the pillar.
