PROBLEM TO BE SOLVED: To provide a manufacturing method of a substrate with a coated film which can thicken the coated film efficiently and hardly causes cracking or film-stripping even when the coated film is thickened, regarding a method for forming the coated film made of inorganic material on the substrate.SOLUTION: A manufacturing method of a substrate with a coated film includes a process of spraying coating liquid which comprises inorganic particles, alkoxysilane hydrolysate and liquid medium onto the substrate retained at a temperature of 200 to 650°C. Therein, an average aggregated particle size of the inorganic particles is less than 100 nm and the liquid medium includes at least one side of polyfunctional hydroxyl group-containing compound and water.SELECTED DRAWING: None |
