INFRARED TEMPERATURE SENSOR AND FUSER USING SAME

摘要

The purpose of the present invention is to provide an infrared temperature sensor the output performance of which can be adjusted without changing the visual field area. An infrared temperature sensor (10) is provided with a case body (20) in which a light guiding path for guiding infrared light incident from an incidence window is provided, a heat conversion film (40) which is disposed to correspond to the light guiding path, absorbs the infrared light that has arrived thereat through the light guiding path, and converts the infrared light into heat, and an infrared sensing element (43) which is disposed on the heat conversion film (40), and an adjustment film (41) is formed on the surface of the heat conversion film (40). By forming the adjustment film (41), the infrared absorptivity of the entire heat conversion film (40) is adjusted to thereby adjust the sensed temperature of the infrared temperature sensor (10). The adjustment film (41) can be configured from ink applied onto the surface of the heat conversion film (40).
