The present claimed invention provides an exhaust gas analysis system using a dilution sampling method with an exhaust gas analysis device that can calculate a measured value such as a concentration of a component to be measured in an exhaust gas with higher accuracy. The exhaust gas analysis device analyzes a diluted exhaust gas as being a mixture of an exhaust gas and a dilution gas that dilutes the exhaust gas, and comprises an analyzing part that measures a component to be measured in the diluted exhaust gas, an introducing path that introduces the diluted exhaust gas into the analyzing part and that has a resistance part as being a flow resistance of the diluted exhaust gas, a viscous component concentration determining part that determines a concentration of a viscous component that is in the diluted exhaust gas and that is different from the component to be measured, and a correction part that corrects the measured value measured by the analyzing part in accordance with the concentration of the viscous component determined by the viscous component concentration determining part.
