PROBLEM TO BE SOLVED: To provide a silicone composition for use in release papers which, even when dissolving by using a nonhalogen solvent, causes no pinholes and no cissing phenomenon and is capable of forming a uniform coated film at the time of coating on a substrate, and is excellent in the releasability, and also gives a cured film which has a small reduction in the adhesive strength of the adhering pressure-sensitive tacky substance. SOLUTION: The silicone composition for use in release papers comprises (A) an organopolysiloxane which has in one molecule at least two of the alkenyl groups bonding to a silicon atom and has in one molecule at least one of the fluorine-containing substituent bonding to a silicon atom, and has a content of a fluorine atom of 20-40 % by mass, (B) an organohydrogenpolysiloxane which has in one molecule at least three of the hydrogen atoms bonding to a silicon atom, (C) a low molecular weight siloxane compound, and (D) a platinum group metal-based catalyst.
