Abstract

In the present invention, slurry is formed by mixing noble metal-supported powder particles () and a binder () with each other in a liquid (Step S), and the noble metal-supported powder particles () are dispersed by applying vibrations to the slurry (Step S), and thereafter, the slurry is spray dried while keeping a state where the noble metal-supported powder particles () are dispersed (Step S), whereby noble metal-supported powder () is produced. In the noble metal-supported powder () produced by such a method, pores through which exhaust gas flows are formed appropriately, and accordingly, exhaust gas purification performance can be enhanced.
