Attained is a heat generative exhaust emission control device with less electric power consumption and with no harmful gas discharged to atmosphere. A porous filter body 7 for capturing particulates in exhaust gas 2 through passing of the exhaust gas 2 is provided with an electric heater 9 so as to heat the filter body 7 ; thus, a heat regenerative particulate filter 10 is provided. The heat regenerative particulate filters 10 are accommodated in filter casings 11 and 12 within an exhaust pipe 3 , and oxidation catalysts 13 and 14 are arranged upstream and downstream of and adjacent to the heat regenerative particulate filter 10 so as to obtain thermo-keeping or heat insulation effect to the heat regenerative particulate filter 10.
