Provided are a coating composition with which an antifouling film having excellent antifouling properties, being transparent, and having durability sufficient for practical use can be formed at low cost; a method of antifouling treatment; and an antifouling substrate. The coating composition comprises a solvent, and dissolved therein, a compound represented by Formula 1 containing a perfluoroalkylene ether group in the molecular main chain and containing a hydrolyzable group containing a silicon atom in a side chain. The solvent is a mixed solvent of fluorinated solvents containing at least one of fluorinated hydrocarbon and fluorinated ether. The fluorinated solvents have a boiling point at 1 atm of 40°C or higher and 70°C or lower, and a difference between the highest and lowest boiling points of the mixed fluorinated solvents is within 25°C. |
