PROBLEM TO BE SOLVED: To prevent both antifouling performance and hydrophilicity in a coating film formed from a conventional coating composition, and has a large amount of organic acid adsorption. SOLUTION: The coating composition of the present invention contains silica fine particles and fluororesin particles, and the coating film formed on the surface of the article is composed of silica particles made of silica fine particles, and the fluororesin particles are silica films. Scattered so as to be partially exposed from the surface, the exposed area of the silica film is larger than the exposed area of the fluororesin particles, and the amount of sodium contained in the coating composition is the amount of silica fine particles The weight ratio with respect to the content was 0.5% or less.
