Abstract: A light detection device includes: a Fabry-Perot interference filter provided with a light transmission region; a light detector configured to detect light transmitted through the light transmission region; a package having an opening and accommodating the Fabry-Perot interference filter and the light detector; and a light transmitting unit arranged on an inner surface of the package so as to close an opening, the light transmitting unit including a band pass filter configured to transmit light incident on the light transmission region. When viewed from a direction parallel to the line, an outer edge of the Fabry-Perot interference filter is positioned outside an outer edge of the opening, and an outer edge of the light transmitting unit is positioned outside the outer edge of the Fabry-Perot interference filter.

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.

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 has a thickness greater than the height of the pillars.
