Abstract:
1. A spectroscopy module comprising: a light-transmitting body portion; a spectroscopic portion for dispersing light made incident from a predetermined plane of the body portion into the body portion, and reflecting the light on the predetermined plane; a light detecting element having a light detecting portion for detecting the light dispersed and reflected by the spectroscopic portion and an external terminal electrically connected to wiring via a bump, the wiring formed on the predetermined plane; and an underfill material filled in the body portion side of the light detecting element and capable of transmitting the light; wherein the light detecting element is provided with a light passing hole through which the light advancing into the spectroscopic portion passes, and a reservoir portion is formed so as to enclose a light outgoing opening of the light passing hole on a plane of the body portion side of the light detecting element.
