A method for producing metal-supported oxide particles in which metal particles are supported on oxide particles, wherein the particle size of metal particles supported on oxide particles can be easily reduced. Providing a method for producing particles. A reverse micelle for preparing a reverse micelle solution (a) containing a salt of one metal M selected from Ag, Ni, and Co, a La salt, a Ca salt, a Mn salt, and an Fe salt is provided. Solution (a) preparation step S11, reverse micelle solution (a), and metal M salt, La salt, Ca salt, Mn salt and Fe salt contained in reverse micelle solution (a) are hydroxylated Mixing step S12 for preparing a reverse micelle solution (A) containing a precursor of metal-supported oxide particles by mixing a reverse micelle solution (b) containing a neutralizing agent to be precipitated as a product, and a reverse micelle solution (A) The metal-supporting oxide particle manufacturing method having a separation step S13 for separating the solid matter from) and a firing step S14 for firing the separated solid matter.
