Abstract
An exhaust gas treating apparatusincludes; a case bodyand a plasma producing meanscapable of producing plasma inside the case bodyand treats the substances to be treated contained in the exhaust gas by the plasma producing means. The plasma producing meanshas one or more each of a pulse electrodeand a ground electrodethat are oppositely disposed in the case bodyand has a pulse power sourcecapable of feeding a pulse current to the pulse electrodeby switching frequency and/or voltage for different values at predetermined time intervals. The substances to be treated contained in the exhaust gas can selectively be treated by switching frequency and/or voltage value for different values at predetermined time intervals so that plasma of a kind adequate for the substances to be treated contained in an exhaust gas is produced between the pulse electrodeand the ground electrode
