PROBLEM TO BE SOLVED: To provide a spectroscopic module with high reliability. SOLUTION: In the spectroscopic module 1, a light detection element 4 has a light passage opening 4b for making light entering a body part 2 pass therethrough. Thereby, the relative positional relationship between the light passage opening 4b and a light detection part 4a of the light detection element 4 is prevented from being deviated. In addition, an optical element 7 guiding light entering into the body part 2 is arranged on the light passage opening 4b. Thereby, light to be entered into the body part 2 can be surely guided without blocking a part of the light to be entered into the body part 2 by a light entering side edge part of the light passage opening 4b. Accordingly, reliability can be improved by the spectroscopic module 1. COPYRIGHT: (C)2009,JPO&INPIT
