An article coated with a coating film having a substrate and, formed on the surface thereof, a coating film containing silicon oxide as a primary component, characterized in that the coating film comprises fine projections and cylindrical projections which are formed by local growth of the above fine projections in the direction of the film thickness or by the local lamination of a plurality of fine particles constituting the above fine projection. The coating film has fine concave and convex portions capable of affording super water-repellency or super-hydrophilicity.
