According to this method, a fatty acid of CnH.sub.2nO.sub.2 (n=5 to 14) is mixed with a plurality of metal sources selected from Zn, In, Sn, Sb, and Al, thereby fatty acid metal salts are obtained, subsequently the fatty acid metal salts are heated at 130° C. to 250° C., and a metal soap that is a precursor is obtained. This precursor is heated at 200° C. to 350° C., and metal oxide primary particles are dispersed in the precursor melt. To this dispersion liquid, a washing solvent having a δP value higher by 5 to 12 than the δP value of the Hansen solubility parameter of the final dispersing solvent is added, thereby the metal oxide primary particles are washed and agglomerated, metal oxide secondary particles are obtained, and then washing is repeated.
