Abstract: A light detection device includes a Fabry-Perot interference filter, a light detector, a spacer that has a placement surface on which a portion outside a light transmission region in a bottom surface of the interference filter is placed, and an adhesive member that adheres the interference filter and the spacer to each other. Elastic modulus of the adhesive member is smaller than elastic modulus of the spacer. At least a part of a lateral surface of the interference filter is located on the placement surface such that a part of the placement surface of the spacer is disposed outside the lateral surface. The adhesive member is disposed in a corner portion formed by the lateral surface of the interference filter and the part of the placement surface of the spacer and contacts each of the lateral surface and the part of the placement surface.

Abstract: The present invention provides a highly reliable spectral module. When light L1 proceeding to a spectroscopic unit (4) passes through a light transmitting hole (50) in the spectral module (1) in accordance with the present invention, only the light having passed through a light entrance side unit (51) formed such as to become narrower toward a substrate (2) and entered a light exit side unit (52) formed such as to oppose a bottom face (51b) of the light entrance side unit (51) is emitted from a light exit opening (52a). Therefore, stray light M incident on a side face (51c) or bottom face (51b) of the light entrance side unit (51) is reflected to the side opposite to the light exit side unit (52) and thus is inhibited from entering the light exit side unit (52). Therefore, the reliability of the spectral module (1) can be improved.
