Disclosed is a heat-conductive silicone composition which contains a cyclic siloxane represented by the following formula (1). In the above formulae, R1 represents a group containing an alkoxysiloxy group having 1-4 carbon atoms; R2 represents a siloxane group represented by the formula (2) above or a monovalent hydrocarbon group having 6-18 carbon atoms; X represents a divalent hydrocarbon group having 2-10 carbon atoms; R 3 represents a monovalent hydrocarbon group having 1-6 carbon atoms or a hydrogen atom; R4 represents a monovalent hydrocarbon group having 1-12 carbon atoms; Y represents a group selected among a methyl group, a vinyl group and R1; and a-d are integers and a >= 1, b >= 1, c >= 0, a + b + c >= 4, d = 2-500.
