PROBLEM TO BE SOLVED: To provide a method of manufacturing a substrate with a coating by using a hydrolyzable silane compound which can easily manufacture the same with high productivity while maintaining quality and a yield by efficiently preparing a coating film-forming composition while suppressing generation of precipitates or the like.SOLUTION: A method of manufacturing a substrate with a coating includes: an A liquid preparing process of preparing an A liquid containing a nonionic surfactant; a B liquid preparing process of preparing a B liquid which contains a hydrolyzable silane compound and/or partial hydrolytic condensate, and silica fine particles, but does not contain the nonionic surfactant; a mixing process of mixing the A liquid and the B liquid stored at a storage temperature of -5°C or lower immediately after the B liquid preparing process at a temperature which does not generate precipitation to obtain a coating film-forming composition; and a coating film-forming process of applying and curing the coating film-forming composition on a substrate to form a coating. |
