Zinc oxide particles having high transparency in visible light and high shielding properties in a ultraviolet region, with surface treatment of inactivating photocatalytic activity applied thereto, and a dispersion thereof. A manufacturing method of surface treated zinc oxide particles, including: a first step of mixing a dispersion liquid with zinc oxide particles dispersed in a solvent, and silicone resin having polysiloxane bond with at least one or more silicon atoms having a silanol group (Si-OH) and/or alkoxy silyl group (Si-OR, wherein R is alkyl group); obtaining a mixed solution containing a surface treated zinc oxide particles precursor, with the silicone resin adsorbed on the surface of each zinc oxide particle and the solvent, and drying and solidifying the mixed solution by applying heat treatment thereto, to thereby manufacture a dried body; and a second step of pulverizing the dried body, to thereby manufacture the surface treated zinc oxide particles.
