For one sample cell, two infrared detectors are installed in optical parallel relationship, and in front of one infrared detector is a filter that transmits only the wavelength at which the amount of radiation from the component to be measured is maximum, and the other infrared detector is placed in front of one infrared detector. In front of each infrared detector, a filter is provided that transmits only wavelengths that are outside the infrared radiation region of the component to be measured and that are close to the aforementioned wavelength, and a divider is provided on the output side of both infrared detectors. An infrared radiation gas analyzer, characterized in that the infrared radiation gas analyzer is configured to measure the concentration of a component to be measured based on the output ratio of both infrared detectors.
