Abstract
There is provided a catalytic converter that offers high exhaust gas cleaning performance by effectively utilizing a whole catalyst that constitutes the catalytic converter. In a catalytic converter (), catalytic layers (A,B) made of a noble metal catalyst are formed on cell wall surfaces of a substrate () having a cell structure, and the catalytic layers (A,B) extend in a longitudinal direction of the substrate () along which gas flows. The substrate () has a central region (A) having a relatively high cell density and a peripheral region (B) having a relatively low cell density. The length of each of the catalytic layers (B) in the longitudinal direction in the peripheral region (B) is longer than the length of each of the catalytic layers (A) in the longitudinal direction in the central region (A).
