Abstract
The exhaust gas cleaning catalyst according to the present invention is provided with a cylindrical substrateand a catalyst coat layerformed on the surface of the substrate. A ratio of the length L in the cylindrical axis direction of the substrateand the diameter D of a cross section orthogonal to the cylindrical axis direction is denoted by (L/D)≤0.8. The coat density of the catalyst coat layerdiffers between an upstream side portionthat includes the exhaust gas inlet-side endof the substrateand a downstream side portionthat includes the exhaust gas outlet-side endof the substrate. The coat density A in the upstream side portionis lower than the coat density B in the downstream side portion(A<B).
