    Abstract: A SERS unit comprises an integrally formed handling board and a SERS element secured within a container space provided in the handling board so as to open to one side in a thickness direction of the handling board. The SERS element has a substrate arranged on an inner surface of the container space and an optical function part formed on the substrate, for generating surface-enhanced Raman scattering.

    Abstract: The present invention provides a highly reliable spectral module. When light L1 proceeding to a spectroscopic unit (4) passes through a light transmitting hole (50) in the spectral module (1) in accordance with the present invention, only the light having passed through a light entrance side unit (51) formed such as to become narrower toward a substrate (2) and entered a light exit side unit (52) formed such as to oppose a bottom face (51b) of the light entrance side unit (51) is emitted from a light exit opening (52a). Therefore, stray light M incident on a side face (51c) or bottom face (51b) of the light entrance side unit (51) is reflected to the side opposite to the light exit side unit (52) and thus is inhibited from entering the light exit side unit (52). Therefore, the reliability of the spectral module (1) can be improved.

    Abstract translation: 本发明提供了一种高度可靠的光谱模块。 当进入分光单元（4）的光L1穿过根据本发明的光谱模块（1）中的透光孔（50）时，仅通过形成光入射侧单元（51）的光 朝向基板（2）变窄并且进入与光入射侧单元（51）的底面（51b）相对形成的光出射侧单元（52）从光出射开口（52a）射出， 。 因此，入射到光入射单元（51）的侧面（51c）或底面（51b）的杂散光M被反射到与光出射单元（52）相反的一侧，因此被禁止进入 光出射侧单元（52）。 因此，可以提高光谱模块（1）的可靠性。

    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.
