An object of the present invention is to provide a coating composition capable of quickly forming a water- and oil-repellent cured film in a simple process. [Solution] (A) At least one type of fluorine-containing organosilicon compound represented by the following formula (1) or (2) Rf 1 -QZ 1 A α (1) A α Z 1 Q-Rf 2 - (Q-Z 2 -Q-Rf 2) x -QZ 1 A α (2) [Wherein, Rf 1 is a perfluoroalkyl group or a perfluorooxyalkyl group, Rf 2 is a perfluorooxyalkylene group, Z 1 is a single bond or a divalent to 9-valent organic group containing 1 to 15 silicon atoms, Z 2 is a divalent polyorganosiloxane group containing 2 to 100 silicon atoms, Q is a 2-9 valent group having 2 to 12 carbon atoms which may contain an oxygen atom and / or a nitrogen atom, provided that in formula (2), they may be different from each other; α is an integer of 1 to 8, x is an integer of 0 to 5, and A is a group represented by the following general formula: —C b H 2b SiR 3-a X a (In the formula, R is an alkyl group having 1 to 4 carbon atoms or a phenyl group, X is a hydrolyzable group, a is 2 or 3, and b is an integer of 0 to 6). And (B) a fluorine-containing carboxylic acid having a number average molecular weight of 100 to 10,000 and containing a fluorine atom of 25% by weight or more of the molecular weight with respect to 100 parts by mass of the component (A), 0.001 -10 parts by mass, A coating agent composition characterized by comprising.
