Abstract: In the spectroscopy module 1, a light detecting element 4 is provided with a light passing opening 4b through which light made incident into a body portion 2 passes. Therefore, it is possible to prevent deviation of the relative positional relationship between the light passing opening 4b and a light detection portion 4a of the light detecting element 4. Further, an optical element 7, which guides light made incident into the body portion 2, is arranged at the light passing opening 4b. Therefore, light, which is to be made incident into the body portion 2, is not partially blocked at a light incident edge portion of the light passing opening 4b, but light, which is to be made incident into the body portion 2, can be guided securely. Therefore, according to the spectroscopy module 1, it is possible to improve the reliability.

Abstract: In the spectroscopy module 1, a light absorbing layer 6 having a light-passing hole 6a through which light L1 advancing into a spectroscopic portion 3 passes and a light-passing hole 6b through which light L2 advancing into a light detecting portion 4a of a light detecting element 4 passes is integrally formed by patterning. Therefore, it is possible to prevent deviation of the relative positional relationship between the light-passing hole 6a and the light-passing hole 6b. Further, since the occurrence of stray light is suppressed by the light absorbing layer 6 and the stray light is absorbed, the light detecting portion 4a of the light detecting element 4 can be suppressed from being made incident. Therefore, according to the spectroscopy module 1, it is possible to improve the reliability.

Abstract: Since a spectroscopic module (1) has a plate-shaped body section (2), the spectroscopic module can be reduced in size by reducing the thickness of the body section (2). Moreover, since the body section (2) is plate-shaped, the spectroscopic module (1) can be manufactured, for example, by using a wafer process. More specifically, by providing lens sections (3), diffraction layers (4), reflection layers (6) and light detecting elements (7) in a matrix form on a glass wafer which becomes many body sections (2) and dicing the glass wafer, many spectroscopic modules (1) can be manufactured. This enables easy mass production of spectroscopic modules (1).
