Abstract
A light detection device includes a Fabry-Perot interference filter provided with a light transmitting region on a predetermined line, a light detector disposed on one side with respect to the Fabry-Perot interference filter on the line, a package having an opening positioned on the other side with respect to the Fabry-Perot interference filter on the line, a light transmitting member provided in the package such that the opening is blocked, and a temperature control element having an endothermic region thermally connected to the Fabry-Perot interference filter and the light detector. The endothermic region is positioned on one side with respect to the light detector on the line.
