    Abstract: PROBLEM TO BE SOLVED: To provide a thermally conductive silicone composition that provides a thermally conductive silicone molding that has high restoration performance in spite of having a low hardness and is excellent in handleability and reworkability; and a thermally conductive silicone molding using the composition.SOLUTION: The thermally conductive silicone composition contains (a) an organopolysiloxane containing an alkenyl group at least in a side chain, wherein the number of the alkenyl groups in the side chain is 2 to 9; (b) an organohydrogenpolysiloxane, wherein at least both terminals are blocked with SiH groups; (c) a thermally conductive filler; and (d) a platinum group metal-based curing catalyst. Assuming that an average number of siloxane bond among silicon atoms in a non-terminal moiety, to each of which silicon atoms the alkenyl group is bonded in the organopolysiloxane, the component (a), is L, and that an average degree of polymerization of the organohydrogenpolysiloxane, the component (b), is L', L'/L=0.6 to 3.0 is satisfied. The thermally conductive silicone molding in the form of a sheet comprises a cured product of the composition.
