<P>PROBLEM TO BE SOLVED: To provide a highly reliable spectroscopic module. <P>SOLUTION: In a spectroscopic module 1 according to the present invention, when light L1 traveling to a spectroscopic part 4 passes through a light passage hole 50, only light which has passed through a light incident side part 51 tapered toward a side of the spectroscopic part 4 and which has been incident onto a light emission side part 52 formed so as to be opposed to a bottom surface 51b of the light incident side part 51 is emitted from a light emission opening 52a. Since stray light M incident onto a side surface 51c and the bottom surface 51b of the light incident side part 51 is therefore reflected to a side opposite to the light emission side part 52, it is possible to reduce incidence of the stray light onto the light emission side part 52. It is therefore possible to improve reliability of the spectroscopic module 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
