Abstract
Provided is a catalytic converter in which the entire catalyst constituting the catalytic converter can be efficiently utilized to purify exhaust gas, and the emission of hydrogen sulfide can be suppressed. A catalytic converterincludes catalyst layersA,B formed of a noble metal catalyst that are formed on cell wall surfaces of a substratehaving a cell structure in a longitudinal direction of the substratein which gas flows, in which the substratehas a center regionA having a relatively high cell density and a peripheral regionB having a relatively low cell density, and lengths of the catalyst layersA,B of the center regionA and the peripheral regionB in the longitudinal direction are the same as each other, or the length of the catalyst layerB in the longitudinal direction is shorter than that of the catalyst layerA.
