Abstract
An infrared detector is arranged so that a detection-input processing circuit part including an infrared sensor mounted on a circuit board is housed as isolated from ambient air in a chamber inhibiting any ambient air inflow, for sensing infrared rays emitted from a human body or the like object as condensed by a condenser irrespective of the ambient air conditions, the sensing ability of the infrared sensor the accuracy of which is likely to be easily deteriorated even with a very small change in the ambient temperature can be thereby stabilized, and a highly accurate infrared detection can be constantly achieved.
