Abstract
Catalyst noble metal particles for exhaust gas purification are formed of an alloy that contains Pt and Pd, wherein the standard deviation σCOM of the composition expressed by the ratio (Pt/(Pt+Pd)) of the mass of Pt to the total mass of Pt and Pd in the catalyst noble metal particles is 3.0% by mass or less.

Noble metal catalyst particles which are noble metal particles of an exhaust gas purification catalyst comprising an alloy containing Pt and Pd,
- wherein the standard deviation σCOM of the composition represented by the ratio of the Pt mass with respect to the total mass of Pt and Pd(Pt/(Pt+Pd)) in the noble metal catalyst particles is 3.0 mass % or lower.
