An exhaust emission control device for an internal combustion engine includes a capturing device that is disposed in an exhaust passage of the engine and that captures particulate matter in exhaust gas flowing through the exhaust passage, a sensor that is disposed in the exhaust passage on a downstream side of the capturing device in a flow direction of exhaust gas and that measures an amount of soot in the particulate matter, a control unit for increasing the particulate matter that flows into the capturing device, and a determination device for determining whether the capturing device is at fault based on the amount of soot measured by the sensor after increasing the particulate matter that flows into the capturing device through the control unit.
