    • An automobile exhaust gas purification catalyst comprised of a support mainly comprised of ZrO2 in which Rh is supported as a catalyst metal preventing sintering of the support, raising the supporting efficiency, and raising the low temperature activity and a method of production of the same are provided. An automobile exhaust gas purification catalyst comprised of a support mainly comprised of ZrO2, sintered under firing conditions where the as fired ZrO2 will substantially not be charged in a catalyst metal supporting treatment solution, in which Rh is supported as a catalyst metal in a particle state. The method of production includes a step of charging the support mainly comprised of ZrO2 fired under the above firing conditions by applying at least one treatment of an acid treatment and a base treatment and a step of dipping the charged state support in the catalyst supporting treatment solution including a colloid of Rh as the catalyst metal to make the Rh colloid be adsorbed on the support.
