Abstract
In the spectroscopy module, a light absorbing layerhaving a light-passing holethrough which light Ladvancing into a spectroscopic portionpasses and a light-passing holethrough which light Ladvancing into a light detecting portionof a light detecting elementpasses is integrally formed by patterning. Therefore, it is possible to prevent deviation of the relative positional relationship between the light-passing holeand the light-passing hole. Further, since the occurrence of stray light is suppressed by the light absorbing layerand the stray light is absorbed, the light detecting portionof the light detecting elementcan be suppressed from being made incident. Therefore, according to the spectroscopy module, it is possible to improve the reliability.
