PROBLEM TO BE SOLVED: To provide an exhaust emission control device capable of reducing the temperature difference in a filter body.SOLUTION: An exhaust emission control device according to an embodiment includes a cylindrical cylinder body through which exhaust gas can flow, a cylindrical filter body disposed in the cylinder body coaxially with the cylinder body, a heating body provided in a prescribed region including an upstream side surface of the filter body, a columnar electrode arranged in the cylinder body coaxially with the cylinder body, and an AC power supply for supplying a high frequency to the electrode. The heating body is made of a material whose absorptivity of an electric field, a magnetic field, or an electromagnetic wave formed between the electrode and the cylinder body is higher than that of the filer body.SELECTED DRAWING: Figure 2A |
