PROBLEM TO BE SOLVED: To reduce the temperature effect on a light irradiation part 5 and a light detection part 6 from an exhaust pipe 12 and an exhaust gas when the exhaust gas from the exhaust pipe 12 is directly measured. SOLUTION: This exhaust gas analyzer is equipped with the inner cylinder 3 arranged so as to be spaced apart outward in the radial direction of the exhaust pipe 12 and fixed to the end part 12A on the opening side of the exhaust pipe 12, the outer cylinder 4 arranged so as to be spaced apart outward in the radial direction of the inner cylinder 3 and fixed to the inner cylinder 3, the light irradiation part 5 attached to the outer cylinder 4 to irradiate the exhaust gas discharged from the exhaust pipe 12 with inspection light La and the light detection part 6 attached to the outer cylinder 4 to detect the scattered light Lc and/or transmitted light Lb from the exhaust gas.
