    Abstract: The present invention is one that accurately measures an exhaust gas component regardless of variation in atmospheric pressure around a test object that is a vehicle or part of it, and an exhaust gas analysis apparatus that measures component concentration in exhaust gas discharged from the test object that is the vehicle or part of it. The exhaust gas analysis apparatus includes: an exhaust gas detector that mixes the exhaust gas and reactive gas together and detects the resulting phenomenon; a pressure gauge that measures the atmospheric pressure at the time of measurement of the exhaust gas or pressure at a predetermined point inside the exhaust gas analysis apparatus as measured pressure; and a correction part that, on the basis of the measured pressure by the pressure gauge, corrects the measurement error of the exhaust gas detector associated with a variation in the supply amount of the reactive gas.
