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.
