計。[Claim for Utility Model Registration] A cell into which a sample fluid is introduced to an infrared irradiation light source, and a plurality of detectors for respectively detecting the concentrations of a plurality of measurement target components in the sample fluid, In a non-dispersive infrared analyzer for multi-component measurement, which is arranged in that order and so that an optical linear relationship is established, the plurality of measurement target components are arranged in front of the foremost detector among the plurality of detectors. A wide band pass filter is provided that includes all the main absorption wavelength bands of infrared rays and has an infrared transmission wavelength band that is set as narrow as possible as a whole, while the first one of the plurality of detectors Immediately in front of each detector other than the detector, the detector is set to include all the main absorption wavelength bands of infrared rays by the components to be measured corresponding to the detector itself and the detectors behind it, and is set as narrow as possible as a whole. 1. A non-dispersive infrared analyzer for multi-component measurement, characterized in that it is equipped with a narrow band pass filter having an infrared transmission wavelength band.
