Metal oxide particles coated with a hydrophobized silicon oxide which are excellent in dispersibility in fluororesins, resistance to fluorochemicals, and ultraviolet-shielding properties; and a fluororesin film excellent in transparency, weatherability, and ultraviolet-shielding properties. The metal oxide particles coated with a hydrophobized silicon oxide are obtained by a production process which comprises: (a) the step of adding a silicon oxide precursor to a dispersion of metal oxide particles to obtain a dispersion of silicon-oxide-coated metal oxide particles; (b) the step of adding a compound (1) or (2) and a silicon oxide precursor to the dispersion to conduct a primary hydrophobizing treatment; (c) the step of subsequently adding a silanol-protective agent to conduct a secondary hydrophobizing treatment; and (d) the step of drying the dispersion. The fluororesin film comprises: the metal oxide particles coated with a hydrophobized silicon oxide; and a fluororesin.
