<p><P>PROBLEM TO BE SOLVED: To suppress leak between electrodes due to accumulation of PM (particulate matters) in an exhaust gas cleaner for cleaning exhaust gas by the action of a high voltage. <P>SOLUTION: The whole surface of a discharge electrode 20 is coated with an insulator 22. Even when a large amount of the PM are accumulated on a path connecting the outer peripheral surface of the insulator 22 with the front end surface of the honeycomb structural body, or on a path from the outer peripheral surface of the insulator 22 to an outer peripheral electrode 15 through the front end surface of the honeycomb structural body 10, leaks due to these paths can be effectively prevented by the insulation between an electrode main body 21 and its outside. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
