Patent ID: 8035814

Claim:
A spectroscopy module comprising: a body portion through which light is allowed to transmit; a spectroscopic portion that disperses a light made incident into the body portion from a side of a predetermined plane of the body portion, and reflects lights to the side of the predetermined plane; a light detecting element which is provided on the predetermined plane, the light detecting element detects the lights dispersed by the spectroscopic portion; and an optical resin adhesive disposed at least between the predetermined plane and a light detecting portion of the light detecting element, wherein, a light passing hole through which a light advancing to the spectroscopic portion passes is formed, and terminal electrodes facing a side opposite to the body portion are provided in the light detecting element, and on a plane at the body portion side of the light detecting element, a first convex portion is formed so as to be located at least between the light detecting portion and the light passing hole when viewed from a direction substantially perpendicular to the predetermined plane.
