PROBLEM TO BE SOLVED: To reduce detection error by preventing incidence of dispersed light, reflected on the teeth of an outlet slit, into other outlet slits, preventing stray lights. SOLUTION: A spectroscope for spectrographic analysis system 1 of the spectrographic analyzer, where an inlet slit 3 for passing an irradiation light 11 from a light source, a dispersion means (reflection/diffraction grating 4) and a plurality of outlet slits 5 for passing a dispersed light 14 are arranged around the Rowland circle 2, is to let a normal 25 to the teeth surface 6 of the outlet slit 5 is not directed to the dispersion means (reflection/diffraction grating 4) side; and it set so as have the dispersion means (reflection/diffraction grating 4) the normal 25 to the teeth 6 of the outlet slit 5 shifted with respect to from the dispersion direction of the outlet slit.
