Exhaust Gas Purifying Catalyst

An exhaust gas purifying catalyst that is disposed in an exhaust path of an internal-combustion engine and purifies an unburnt component in exhaust gas emitted from the internal-combustion engine, comprising:

• a base material;
• a reforming reaction layer provided on the base material and including at least one of a rare earth oxide and a transition metal oxide (except precious metal other than Rh and Ru) as a hydrogen generation catalyst that converts the unburnt component in the exhaust gas into H2;
• and
• a catalyst layer including precious metal that purifies the unburnt component, wherein a content of the hydrogen generation catalyst in the reforming reaction layer is 5 g/L or more per unit volume of the base material.
