Abstract

Provided is a catalyst converter for purifying exhaust gas and a method for manufacturing the catalyst converter, in which a heater is disposed between inner/outer monoliths, to thereby heighten a heat transfer efficiency and induce a uniform catalytic reaction, and to thereby enhance a processing performance, and minimize an electric power consumption and miniaturize a device. The catalyst converter includes: a heater having a winding portion which is wound so as to have a space therein and a pair of electric power terminals; inner and outer monoliths which are inserted in the inner and outer circumferential portions of the heater winding portion wherein each of the inner and outer monoliths includes a number of hollow cells on the surfaces of which catalysts have been coated and which are formed in the lengthy direction; and a housing in which a support assembly is assembled.
