摘要： An automobile exhaust gas catalytic converter includes a first catalyst layer; a second catalyst layer located on a downstream side as compared to the first catalyst layer; and a base material on which the first catalyst layer and the second catalyst layer are respectively located. In the exhaust gas catalytic converter, the proportion (LB/LS) of a coating length (LB) of the second catalyst layer from a downstream end of the base material with respect to a total length (LS) of the base material in the exhaust gas flow direction is approximately 50 to 90%, the proportion of an amount of Rh contained in the second catalyst layer with respect to a total amount of Rh contained in the first catalyst layer and the second catalyst layer is approximately 50 to 90% by mass, and the rest of Rh is contained together with Pd or Pt in the first catalyst layer.
