Patent ID: 8368885

Claim:
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 supported on the predetermined plane to detect the light dispersed and reflected by the spectroscopic portion; wherein the light detecting element is provided with a light passing opening through which the light made incident into the body portion passes, and an optical element for guiding the light made incident into the body portion is arranged on the light passing opening, wherein the light passing opening is one through which the light advancing to the spectroscopic portion passes, wherein the optical element is one for guiding the light advancing to the spectroscopic portion, and wherein the body portion is provided with first and second light-transmitting members, the first light-transmitting member including the predetermined plane, and the second light-transmitting member including an outer surface, the spectroscopic portion is formed on the outer surface of the second light-transmitting member, and a wiring is formed on the predetermined plane, the wiring being provided with a plurality of first pad portions, a plurality of second pad portions and a plurality of connection portions for connecting corresponding first pad portions and second pad portions, and, an external terminal of the light detecting element is electrically connected to the first pad portions.
