PROBLEM TO BE SOLVED: To provide an inorganic coating composition which is suitable for preventing contamination of a coated film surface of a coated product and has excellent durability, and a method for producing the same. SOLUTION: (A) It has a repeating structural unit of a general formula R a SiO (4-a) / 2 (R is a monovalent hydrocarbon group, and a is 0.8 to 1.8). A polyorganosiloxane having at least 10% by weight of bonded alkoxyl groups, A mixture comprising (B) a hydrophilic organic solvent and (C) water was mixed with 4 The hydrolysis product of the polyorganosiloxane obtained by heat treatment at 0 ° C. or more has (D) a general formula R ′ b SiX (4-b) (R ′ is a hydrocarbon group, b is an integer of 0 to 3, X is a hydrolyzable organic silane compound having a hydrolyzable group), and (E) a metal chelate compound and / or metal alcoholate, followed by heat treatment at 40 ° C. or more, and an inorganic coating composition obtained therefrom.
