PROBLEM TO BE SOLVED: To obtain a coating material capable of expressing excellent effects such as antifouling, antifungal, antibacterial and deodorizing properties, weatherability, glossiness and the like for a long time by coating the coating material (the same) on the surface layers of automobile bodies and the like. SOLUTION: This coating material contains 100-10,000 wt.ppm colloidal solution of an antibacterial inorganic oxide in which fine particles consisting of an antibacterial metal component and the inorganic oxide except the antibacterial metal component are dispersed as based on the fine particles and 0.1-10 wt.% surfactant such as a nonionic surfactant or the like. The fine particles have >=1.50 refractive index and 3-500 nm average particle size. The weight ratio (the surfactant/the particles) of the surfactant to the fine particles in the colloidal solution is in the range of 0.5-50.
