PROBLEM TO BE SOLVED: To provide a radiation thermometer capable of being constituted in a small size and at low cost. SOLUTION: The radiation thermometer comprises an optical system 2 for condensing a radiation energy from an object 1 to be measured, spectral means 31 to 3N for spectrally separating the light condensed by the system 2, a detecting element 4 for detecting the light of the object to be measured spectrally separated by the means 31 to 3N, and a microcomputer 5 inputting a necessary other signal such as an analog output of the detector 4, a set signal of a set means or the like to calculate as prescribed to measuring a temperature.
