PURPOSE:To aim at improving dissociation and elimination effect of NOx is exhaust by providing an electrode holding member consisting of porous insulating material and including honeycomb passages in an exhaust passage and providing conductive bodies in the honeycomb passages. CONSTITUTION:An electrode holding member consisting of porous insulating material and including many honeycomb passages 6. In the honeycomb passages 6 are provided conductive bodies 4. With the conductive bodies 4 is connected a high voltage generator 5. Contacting area and duration between exhaust and a discharge field are expanded by this, and dissociation and elimination effect of NOx in exhaust can thus be improved.
