In a spectroscopy module 1, a light detecting element 5 having a light passing hole 50 is used. Therefore, it is possible to prevent the relative positional relationship between the light passing hole 50 and a light detecting portion 5a of the light detecting element 5 from deviating. Moreover, the light detecting element 5 is electrically connected to a wiring 9 formed on a front plane 2a of a substrate 2 by face-down bonding, and a resin layer 79 is formed as an underfill resin between the substrate 2 and the light detecting element 5.
