PROBLEM TO BE SOLVED: To provide a chip for measuring Raman scattered light emitted from a sample with high sensitivity.SOLUTION: The Raman scattered light measurement chip has a measurement unit including: a base; a sample holder which is disposed facing to the base; and a sample receiver disposed between the base and the sample holder. A light wavelength selection area is formed on a plane of the base which is in contact with the sample receiver. The light wavelength selection area transmits illumination light irradiated to the sample in the sample receiver from the base side, and reflects Raman scattered light which is generated due to excitation light irradiated to the sample in the sample receiver from the sample holder side and is emitted from the sample. The sample holder has optical transparency in at least a part opposing to the light wavelength selection area. |
