A curable silicone composition that cures at room temperature into a highly water-repellent, highly oil-repellent film is obtained from a composition of (A) an organopolysiloxane resin with the following average unit formulaRa(ZO)bSiO(4-a-b)/2in which R represents substituted and unsubstituted monovalent hydrocarbon groups, Z is a hydrogen atom or C1 to C6 alkyl group, i has a value from 0.80 to 1.80, and b has a value that gives a content of 0.01 to 10 weight % silicon-bonded hydroxyl or alkoxy in the instant compound; (B) an organopolysiloxane each molecule of which contains at least one silylalkylene group with the following general formula bonded to main-chain silicon-R1-SiR2(3-m)Xmwherein R1 represents alkylene and alkyleneoxyalkylene groups; each R2 is a group independently selected from the set consisting of alkyl groups, aryl groups, and the 3,3,3-trifluoropropyl group; X is a halogen atom or, alkoxy group; and m is an integer from 1 to 3, and each molecule of organopolysiloxane (B) contains at least one fluorine-containing organic group with the following general formula bonded to main-chain silicon-R1-CnF(2n+1)wherein R1 is defined as above and n is an integer with a value of at least 4; (C) an organosilane with the general formulaRcSiY4-cR represents substituted and unsubstituted monovalent hydrocarbon groups, Y is a hydrolyzable group, and c is an integer from 0 to 2 or the partial hydrolysis and condensation product thereof; and (D) a cure-accelerating catalyst.
