Exhaust gas purifying catalyst and method for producing same

A method for producing an exhaust gas purifying catalyst, comprising:

• a step of preparing a support having an oxygen absorbing/releasing ability,
• a step of obtaining a precursor-coated support by coating the surface of said support with a precursor for giving a thin layer containing Al and O and having a thickness corresponding to from 1 to 2 times the diameter of one Al atom,
• a step of preparing an acid salt of Co and an acid salt of a metal M (M is a metal element selected from Cu, Mn, Ni, Fe, Mg and Ag),
• a step of producing a precursor of a solid material composed of M, Co and O from said acid salt of Co and said acid salt of a metal M, and
• a step of depositing said solid material precursor on the precursor-coated surface of said precursor-coated support.
