Abstract
A non-contact temperature sensor includes a holder serving as a light conducting portion for guiding infrared rays incident from a first opening at its one end; a plastic film arranged at a second opening of the other end of tile light conducting portion; a cover for sealing the second opening at the other end of the holder so as to provide a space between itself and the plastic film, an infrared ray detection heat-sensitive element arranged on the side of the space of the plastic film, for detecting the infrared rays incident from the first opening; and a temperature compensating heat-sensitive means arranged in the vicinity of the holder, for detecting the temperature of the holder. In this configuration, the surface temperature of the body-to-be-detected can be precisely detected in a short time.
