Abstract: A method for manufacturing conductive inorganic oxide particles in which conductivity is furnished by doping a dopant metal component into the inorganic oxide particle including preparing an inorganic oxide particles-containing slurry which contains the inorganic oxide particles, the inorganic oxide particles-containing slurry which is made to contain a dopant metal component and an electrolysis method is carried out for electrolytic doping to dope a dopant metal component into the inorganic oxide particles by using a electrolytic doping unit, filtering and drying the slurry after finishing the electrolytic doping and collecting particles by filter, and firing the particles collected by filter to obtain conductive inorganic oxide particles.
