ABSTRACT:
A first thermistor8and a second thermistor9are arranged forwardly and rearwardly of a thermopile sensor5. A thermopile chip55is arranged and interposed between the first thermistor8and an integrated thermistor57. A sensor cover is mounted in contact with front and side portions of a can portion59of a thermopile casing56. A temperature or a radiant quantity of infrared rays on the front portion of the can portion is estimated from a temperature change of the integrated thermistor per second.
