Abstract
A catalyst layer includes: a first mixed oxide particle componentwhich contains Ce and Rhand in which Rh is partially exposed at particle surfaces; and a second mixed oxide particle componentcontaining Ce, Zr, and a rare earth metal except Ce. The particle size distribution of the first mixed oxide particle componenthas a peak in the particle size range from 100 nm to 300 nm, both inclusive. The particle size distribution of the second mixed oxide particle componenthas a peak in a particle size range larger than the particle size range in which the first mixed oxide particle componenthas the peak. At least part of particles of the first mixed oxide particle componentis attached to at least part of particles of the second mixed oxide particle component
