Claim 0:
1. A non-curable thermal-conductive silicone composition comprising essential components of:
(A) an organopolysiloxane having a kinematic viscosity at 25° C. of 1,000,000 mm2/s or more and contained in an amount of 5 to 20 mass % relative to a sum of the component (A) and a component (B);
(B) a hydrolysable organopolysiloxane compound shown by the following general formula (1) and contained in an amount of 80 to 95 mass % relative to the sum of the component (A) and the component (B),, , wherein R1's each represent a monovalent hydrocarbon group having 1 to 10 carbon atoms optionally having a substituent and are identical to or different from one another, and “m” represents an integer of 5 to 100; and
(C) at least one heat conductive filler selected from the group consisting of metals, metal oxides, metal hydroxides, metal nitrides, metal carbides, and carbon allotropes, wherein the component (C) is contained in an amount of 10 to 95 mass % relative to a total amount of the composition,
wherein a mixture of the component (A) and the component (B) has a molecular weight distribution Mw/Mn of 10 or more.
