PROBLEM TO BE SOLVED: To provide a high-precision infrared gas analyzer in which changes in temperature within a case and influences of outside air temperature are small as much as possible. SOLUTION: The infrared gas analyzer comprises an analyzing part 2 and an electronic power supply part 10, as well as fan 11 to discharge heat generated by a light source 5 for the analyzing part 2 and the electronic power supply part 10 from the case 1, all of which are located inside of the case 1 to prevent influences of outside air temperature. A rotating speed of the fan 11 is controlled according to output 7a from a temperature sensor 7 located in the case 1 for temperature correction of output 6a from a detector of the analyzing part 2.
