Abstract

Provided is a thermally conductive thin-film cured product constituted by a cured product of a handleable silicone composition, the cured product having good transferability to a member and good post-debonding handling properties, and exhibiting good bond strength to a heat-generating element, even at elevated temperatures. The thermally conductive thin-film cured product is obtained by curing a silicone composition containing: (a) 100 parts by mass of an organopolysiloxane comprising two or more alkenyl groups per molecule; 200-2,000 parts by mass, inclusive, of a thermally conductive filler; (c) an amount of an organohydrodiene polysiloxane comprising two or more hydrogen atoms directly bonded to a silicon atom per molecule such that Si—H/alkenyl groups is 0.5-50.0, inclusive; (d) an amount of a platinum group metal compound equal to 0.1-1,000 ppm (mass), inclusive, with respect to component (a) in terms of the mass of the platinum group metal element; (e) a reaction regulator, as required; (f) 50-300 parts by mass, inclusive, of a silicone resin; and (g) 0.1-20 parts by mass, inclusive, of an adhesive component selected from (g-1) or (g-2).
