[PROBLEMS] To provide an exhaust gas purifying catalyst capable of efficiently purifying HC among CO, NO and NOx in exhaust gas discharged at a low temperature immediately after starting an engine. SOLUTION: In an integrated structure type catalyst having a catalyst component supporting layer, a first layer mainly composed of zeolite is provided on a monolithic carrier, and palladium (Pd), platinum (Pt) as a catalyst component is provided on the first layer. ) And rhodium (Rh). The first layer and / or the catalyst component layer contains an ultra-high hydrophobic material. |
