Abstract: To provide an exhaust emission control device for an internal combustion engine, for enabling accurate deterioration determination processing even when the temperature of a selective reduction type NOx catalyst changes.SOLUTION: The exhaust emission control device for the internal combustion engine includes: an SCR catalyst; a reductant supply device for supplying a precursor of ammonia or the ammonia as reductant to the upstream of the SCR catalyst; a sensor for detecting ammonia slip concentration; and a determination device for determining that the SCR catalyst has deteriorated when the detected ammonia slip concentration exceeds a determination threshold value, while supplying the SCR catalyst with the reductant whose amount is enough for ammonia slip to develop at the time of catalyst deterioration. The determination device executes the deterioration determination processing when determination conditions that a normal concentration upper limit value falls below a deterioration concentration lower limit value are established. The determination threshold value is equal to or greater the normal concentration upper limit value and smaller than the deterioration concentration lower limit value.SELECTED DRAWING: Figure 8
