    摘要： A catalyst converter includes: a substrate (1) having a cell structure formed of a center area (1A) having the highest cell density, a peripheral area (1C) having the lowest cell density, and an intermediate area (1B) 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 (1A); a second catalyst layer formed in the intermediate area (1B); and a third catalyst layer formed in the peripheral area (1C). 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.

    摘要： A catalytic converter (10) includes i) an outer tube (1) that includes a cylindrical portion (1a), an upstream-side cone portion (1b), and a downstream-side cone portion (1c), and ii) a substrate (2) having a cell structure that is arranged in the cylindrical portion (1a) of the outer tube (1). The substrate (2) has a center region (2a) where a cell density is relatively high and a peripheral region (2b) where the cell density is relatively low, in a cross-section that is orthogonal to a length direction of the substrate (2). A projection portion when a connecting portion (5) of the exhaust duct (4) and the downstream-side cone portion (1c) is projected onto the substrate (2) is within the center region (2a).
