<p>PURPOSE:To improve the infrared detection response of an infrared detecting element by making the entire body of the detecting element simpler and smaller in size by eliminating such inconvenience that a desired lens must be fitted to the outside of the detecting element when the detecting element is used for detecting a human body, etc., and, at the same time, eliminating the light loss caused by the lens. CONSTITUTION:This infrared detecting element has an infrared ray transmissive filter 3 provided on the upper surface of a hermetic-sealed case 1 and an infrared ray photodetector 4 for detecting infrared rays transmitted through the filter 3 provided in the case 1. In addition, the filter 3 is integrally formed with a lens R.</p> |
