Silicone resin composition, thermally conductive sheet, and organopolysiloxane

Abstract

Provided is a silicone resin composition that retains flowability even at high levels of filling with a thermally conductive filler, and that provides suppression of oil bleed during use. This silicone resin composition comprises: as a component (A), an organopolysiloxane that is represented by formula (1) and has a molecular weight distribution (Mw/Mn) of not more than 1.30; and, as a component (B), a thermally conductive filler. (In Formula (1), each R1 independently represents a monovalent saturated hydrocarbon group or a monovalent aromatic hydrocarbon group, each R2 independently represents a monovalent saturated hydrocarbon group, X represents oxygen or a divalent hydrocarbon group, n is an integer equal to or greater than 1, and a is an integer from 1 to 3.)
