To provide an exhaust emission control device capable of suitably burning and removing soot or SOF adhering and accumulating on an electrode of a plasma generating device.

The exhaust emission control device equipped with an after-treatment device (catalyst regeneration type particulate filter 10) making exhaust gas 8 passing therethrough and purifying the same in a middle of an exhaust pipe 9 of an internal combustion engine (diesel engine 1) is provided with the plasma generating device 11 generating plasma by carrying out electrical discharge in the exhaust gas 8 in an upstream side of the after-treatment device, a flow through type oxidation catalyst 12 installed in a preceding stage of the plasma generating device 11, a fuel adding means (control device 17) adding fuel in the exhaust gas 8 in an upstream side of the oxidation catalyst 12, and a temperature raising means (intake air throttle valve 22 or control device 17) raising exhaust gas temperature to temperature enabling oxidation reaction of the fuel added by the fuel adding means in the oxidation catalyst 12.
