Abstract: A SERS element comprises a substrate having a front face; a fine structure part formed on the front face 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 and a plurality of protrusions protruding from the base part at respective positions corresponding to the pillars. The base part is formed with a plurality of grooves surrounding the respective pillars when seen in the projecting direction of the pillars, while an end part of the protrusion is located within the groove corresponding thereto.

Abstract: An SERS element includes a substrate, a fine structure portion formed on a surface of the substrate and having a plurality of pillars, and a conductor layer formed on the fine structure portion and constituting an optical functional portion that causes surface-enhanced Raman scattering. A groove is provided in an outer surface of each pillar. A plurality of gaps are formed in the conductor layer by forming the conductor layer on the outer surface of each pillar in a state in which at least a portion of an inner surface of the groove is exposed.
