A spectrometer 1A is constituted with an optical body 10, a glass member 11 formed with a light entry slit 12, and a connecting flange 20. The connecting flange 20 is provided with an opening 21 to which the glass member 11 is positioned and inserted, and with positioning rods 25 provided in positions in front of and behind the opening 21 as positioned relative to the opening 21. Using the positioning rods 25, when the spectrometer 1A is applied to the measuring apparatus, makes it possible to connect the spectrometer 1A and other components of the measuring apparatus through a passive alignment method simply with high accuracy. Thus, a spectrometer capable of favorably achieving optical connection to light to be optically separated and a measuring apparatus using the spectrometer can be realized.
