Abstract
An exhaust gas purifier uses a honeycomb of an electrically non-conductive material, formed with a plurality of longitudinally extending throughholes through which an exhaust gas is adapted to flow. A conductive layer is formed with an electrically conductive material on inner surfaces of parts of the honeycomb, including at least a portion of each end surface of the honeycomb and a selected center portion of the honeycomb longitudinally extending between the end surfaces where the flow rate of the exhaust gas is higher than elsewhere inside the honeycomb.
