Abstract
An exhaust gas-purifying catalyst includes first particles of oxygen storage material, second particles of one or more alkaline-earth metal elements and/or compounds thereof interposed between the first particles, and third particles of one or more precious metal elements interposed between the first particles. A spectrum of a first characteristic X-ray intensity for one of the one or more alkaline-earth metal elements and a spectrum of a second characteristic X-ray intensity for one of the one or more precious metal elements that are obtained by performing a line analysis using energy-dispersive X-ray spectrometry along a length of 500 nm have a correlation coefficient σ(AE,PM) of 0.70 or more.
