SPECTROSCOPIC MODULE

摘要

In this spectroscopic module (1), a light detecting element (4) has a light passing opening (4b) through which light entering a body section (2) passes. Therefore, the displacement of the relative positional relationship between the light passing opening (4b) and a light detecting section (4a) of the light detecting element (4) can be prevented from occurring. Moreover, an optical element (7) for guiding the light entering the body section (2) is placed in the light passing opening (4b). Consequently, light to enter the body section (2) can be certainly guided without part of the light to enter the body section (2) being blocked off by the edge on the light-entering side of the light passing opening (4b). Accordingly, this spectroscopic module (1) enables improved reliability.
