摘要： An infrared gas analyzer includes: a sample cell through which a sample gas containing a measurement component that absorbs an infrared light flows; one or a plurality of light sources that emits the infrared light; and a detector that detects a concentration of the measurement component contained in the sample gas by utilizing a change in the infrared light being absorbed by the measurement component when the sample gas passes through the sample cell. The detector includes: a first chamber in which a detection gas containing the measurement component is filled and which is irradiated with the infrared light passed through the sample cell; a second chamber in which the detection gas containing the measurement component is filled and which is irradiated with the infrared light passed through a passage different from the sample cell; a gas flow channel which is arranged between the first chamber and the second chamber and through which the detection gas flows between the two chambers; and a first and a second thermal flow sensors arranged in the gas flow channel. The first and the second thermal flow sensors are arranged in the same direction at different positions in which flow directions of the detection gas in the gas flow channel are different from each other.
