Abstract
A spectroscopic module includes a plurality of beam splitters that are arranged along an X direction; a plurality of bandpass filters disposed on one side in a Z direction with respect to the plurality of beam splitters facing the plurality of beam splitters, respectively; a light detector disposed on the one side in the Z direction with respect to the plurality of bandpass filters and including a plurality of light receiving regions facing the plurality of bandpass filters, respectively; a first support body supporting the plurality of beam splitters; and a second support body supporting the plurality of bandpass filters. The second support body includes a support portion in which a support surface is formed so as to be open to the one side in the Z direction. The plurality of bandpass filters are disposed on the support surface.
