PROBLEM TO BE SOLVED: To provide inorganic oxide fine particles which facilitate reduction in a storage space and a transportation space, which can be easily dispersed in a hydrophobic medium such as a resin and an organic solvent, and which are used for forming a coating film that has high transparency and high hardness and is excellent in scratch resistance, adhesiveness to a substrate, weather resistance and light fastness.SOLUTION: Surface-modified inorganic complex oxide fine particles are obtained by subjecting inorganic complex oxide fine particles to surface modification with an organic silicon compound (A) or a partial hydrolysate thereof expressed by general formula (1):Si(OR)(OH)and with an organic silicon compound (B) or a partial hydrolysate thereof expressed by formula (2):RSi(OR) and having a boiling point of 120°C or lower under normal conditions; and the surface-modified inorganic complex oxide fine particles have 2 to 10 wt.% content of carbon atoms.
