Abstract
A catalyst converter includes: a substrate () having a cell structure formed of a center area (A) having the highest cell density, a peripheral area (C) having the lowest cell density, and an intermediate area (B) having the cell density between that of the center area and that of the peripheral area; a first catalyst layer formed in the center area (A); a second catalyst layer formed in the intermediate area (B); and a third catalyst layer formed in the peripheral area (C). A length in a longitudinal direction of the second catalyst layer is longer than that of the first catalyst layer. A length in the longitudinal direction of the third catalyst layer is longer than that of the second catalyst layer. A ratio of the length in the longitudinal direction of the first catalyst layer to the length of the substrate is 65% or more.
