    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 translation: SERS元件包括具有正面的基板; 形成在前表面上并具有多个支柱的精细结构部件; 以及形成在微细结构部分上并构成用于产生表面增强拉曼散射的光学功能部分的导体层。 导体层具有沿着前表面形成的基部和在与支柱对应的各个位置处从基部突出的多个突起。 当沿柱的突出方向观察时，基部形成有围绕相应柱的多个槽，而突起的端部位于与其对应的槽内。

    Abstract: A light detection device includes: a first support part disposed on a mounting surface of the wiring board; a Fabry-Perot interference filter disposed in a first support region of the first support part; and a temperature detector, wherein the temperature detector is disposed on the mounting surface such that at least a part of the temperature detector overlaps a part of the Fabry-Perot interference filter when seen in a first direction perpendicular to the mounting surface and such that at least a part of the temperature detector overlaps a part of the first support part when seen in a second direction in which the first support part and the light detector are aligned with each other, and wherein a first distance between the temperature detector and the first support part in the second direction is smaller than a first width of the first support region in the second direction.
