The present invention provides a highly reliable spectral module. When light Lproceeding to a spectroscopic unit () passes through a light transmitting hole () in the spectral module () in accordance with the present invention, only the light having passed through a light entrance side unit () formed such as to become narrower toward a substrate () and entered a light exit side unit () formed such as to oppose a bottom face () of the light entrance side unit () is emitted from a light exit opening (). Therefore, stray light M incident on a side face () or bottom face () of the light entrance side unit () is reflected to the side opposite to the light exit side unit () and thus is inhibited from entering the light exit side unit (). Therefore, the reliability of the spectral module () can be improved.

Spectral module and method for manufacturing spectral module

In a spectroscopy module, a light passing holethrough which a light Ladvancing to a spectroscopic portionpasses is formed in a light detecting element. Therefore, it is possible to prevent the relative positional relationship between the light passing holeand a light detecting portionof the light detecting elementfrom deviating. Moreover, the light detecting elementis bonded to a front planeof a substratewith an optical resin adhesive. Thus, it is possible to reduce a stress generated onto the light detecting elementdue to a thermal expansion difference between the light detecting elementand the substrate. Additionally, the light transmissive platecovers a part of a light incident opening. Thus, a light incident side surfaceof the optical resin adhesivebecomes a substantially flat plane in the light passing hole. Therefore, it is possible to make the light Lappropriately incident into the substrate
