ABSTRACT:
An infrared sensor is composed of an optical filter plate, an infrared-detecting plate and a supporting member positioned between both plates. A detecting element for detecting infrared rays passing through the optical filter plate is formed on a front surface of the infrared-detecting plate facing the optical filter plate. The supporting member is positioned to surround the detector element on the infrared-detecting plate to firmly connect both plates and to form a predetermined gap between both plates. The supporting member may be composed of a number of discrete dots positioned to surround the detector element or of a continuous ring surrounding the detector element.
