The present invention provides an inexpensive thermoconductive silicone rubber composite sheet having good thermal conductivity, electrical insulation, strength, flexibility, durability due to improvement in interlaminar adhesion, and suitable for automatic packaging with high rigidity. (A) the intermediate layer is an electrically insulating synthetic resin film layer having a thermal conductivity of 0.20 W / m ยท K or more and a tensile elastic modulus of 5 GPa or more, and (B) ) Outer layer comprises at least one selected from the group consisting of (a) an organopolysiloxane, (b) a curing agent, (c) a thermally conductive filler, and (d) an epoxy group, an alkoxy group, a methyl group, a vinyl group and a Si- Wherein the silicone rubber layer is a cured product of a composition comprising a silicone compound-based adhesive property-imparting agent having a group of the following formula (1). |
