Summary:An object of the present invention is to provide zirconium oxide nanoparticles having large particle diameters. The present invention is zirconium oxide nanoparticles wherein a ratio CD90/D50) of a cumulative 90% particle diameter D90 by volume to a cumulative 50% particle diameter D50 by volume in particle diameter measurement by a dynamic light scattering method is not larger than 3.0, and a half width for a (101) plane in XHD measurement in which CuKα rays are used as a light source is not larger than 1.20°. The zirconium oxide nanoparticles preferably have a diffusion coefficient in particle diameter measurement by a dynamic light scattering method of not larger than 7.0×10−7 cm2/sec.
