Zusammenfassung:	[Problem] To provide a coating film capable of more reliably obtaining excellent water repellency and oil repellency. [Solution] The present invention pertains to a water- and oil-repellent coating film formed on the surface of a material in order to impart water repellency and oil repellency, the coating film being characterized in that (1) the coating film contains metal oxide composite particles, (2) the metal oxide composite particles contain a) metal oxide particles and b) a coating layer containing polyfluoroalkyl methacrylate resin formed on the surface thereof, and (3) the value obtained by dividing the fluorine content (wt%) of the metal oxide composite particles by the surface area (m2/g) of the metal oxide particles is 0.025 to 0.180. L'invention concerne un film de revêtement permettant d'obtenir un caractère hydrofuge et un caractère oléofuge de manière plus fiable. La présente invention concerne un film de revêtement hydrofuge et oléofuge formé sur la surface d'un matériau afin de conférer un caractère hydrofuge et un caractère oléofuge, le film de revêtement étant caractérisé en ce que (1) le film de revêtement contient des particules de composite d'oxyde de métal, (2) les particules de composite de métal contiennent a) des particules d'oxyde de métal et b) une couche de revêtement contenant une résine de poly(méthacrylate de fluoroalkyle) formée sur sa surface et (3) la valeur obtenue en divisant la teneur en fluor (% pds) des particules de composites d'oxyde de métal par la surface spécifique (m2/g) des particules d'oxyde de métal est de 0,025 à 0,180.
