Monolith, catalyst convertor for purifying exhaust gas using the same and method for manufacturing the catalyst convertor

A catalyst converter for purifying exhaust gas, the catalyst converter comprising:

• a heater having a winding portion which is wound so as to have a space therein and a pair of electric power terminals which are extended to both sides from the winding portion;
• an inner monolith called a catalyst support which is inserted in an inner circumferential portion of the heater winding portion wherein the inner monolith comprises a number of hollow cells on surfaces of which a catalyst has been coated and which are formed in a lengthy direction;
• an outer monolith called a catalyst support which is inserted in an outer circumferential portion of the heater winding portion wherein the outer monolith comprises a number of hollow cells on surfaces of which a catalyst has been coated and which are formed in the lengthy direction;
• and
• a housing which comprises an inlet through which the exhaust gas to be processed is introduced and an outlet through which processed exhaust gas is exhausted near both side ends thereof, wherein a support assembly where the inner monolith and the outer monolith are assembled in inside/outside of the heater winding portion is assembled in the housing.
