Abstract:
A spectral colorimetric apparatus comprises a light source, a spectral element, a light receiving element, a substrate on which the light receiving element is mounted, a housing and a pressing portion. The housing has a first side wall on which the substrate is fixed and a second side wall on which the spectral element is fixed. The pressing portion pinches the spectral element together with the second side wall and presses the spectral element to the second side wall.
