PROBLEM TO BE SOLVED: To provide a spectrometer and a storage case capable of inhibiting intrusion of external light and improving measurement accuracy.SOLUTION: A biological examination device 1 includes: a measurement module 10 that acquires luminous energy of light at a wavelength of a measurement target included in incident light; and a casing 20 that stores the measurement module 10 and has a window 23 to pass the light propagating toward the measurement module 10. The casing 20 includes an adhesive member 24 disposed in a region enclosing at least the window 23 on a surface 22A of the casing 20. The adhesive member 24 includes a light-shielding part 241 blocking light in a measurement wavelength region including at least the wavelength of the measurement target, which is located outside the window 23 and enclosing the window 23 in a plan view in a direction along an optical axis L of the light propagating toward the measurement module 10.SELECTED DRAWING: Figure 2 |
