PROBLEM TO BE SOLVED: To provide a coating composition and a coating film capable of forming a coating film for giving self-cleansability to e.g. any base such as sheathing surface without degrading/deteriorating the base, and also preventing even a small amount of water from adhering in granules on such surface. SOLUTION: The coating composition comprises visible ray-transparent metal oxide microparticles and a water-soluble methyl silicate or a water-soluble ethyl silicate obtained by hydrolyzing methyl silicate or ethyl silicate with excess water. In this coating composition, the content of the metal oxide microparticles may be 1-25 wt.% and that of the water-soluble methyl silicate or the water-soluble ethyl silicate may be 1-25 wt.%. The coating film has a thin film layer formed from the coating composition. COPYRIGHT: (C)2008,JPO&INPIT
