The present invention is easy to apply at the initial stage, and does not cure at room temperature with moisture, but thickens at room temperature, making it difficult to sag while maintaining softness. In addition, it has good reworkability and is refrigerated for storage. There is no need for heating and freezing, no heating process is required during assembly, poor viscosity increase is unlikely to occur, the manufacturing method is simple, and a room temperature moisture thickened thermal conductive silicone grease composition that can achieve high thermal conductivity is provided. To do. (A) Both end trialkoxysilyl group-blocked organopolysiloxane having a viscosity at 25 ° C. of 0.1 to 1,000 Pa · s, (B) The following formula (1) (R 1 is a monovalent hydrocarbon group, R 2 is an alkyl group, an alkoxyalkyl group, an alkenyl group or an acyl group, n is 5 to 100, and a is 1 to 3. ) An organopolysiloxane represented by (C) a thermally conductive filler having a thermal conductivity of 10 W / m · ° C. or higher, (D) A room temperature moisture thickened thermally conductive silicone grease composition containing a condensation catalyst as an essential component.
