    Abstract: PROBLEM TO BE SOLVED: To provide a heat radiation member having an excellent heat radiation property over a long period of time in the form of a sheet or a film at room temperature. SOLUTION: The heat radiation member forms an intermediate layer having a metal foil and/or a metal mesh whose thickness is 1-50 μm and heat conductivity is 10-500 W/mK, a layer comprising a heat conduction composition containing a silicone resin of 100 pts.wt., and a heat conduction filler of 1,000-3,000 pts.wt. on both the faces of the intermediate layer. The whole thickness is made in a range of 40-500 μm. The heat radiation member has non-fluidity at the room temperature, produces low viscosity based on phase transition of the resin and a low melting metal, softening or melting due to the generated heat when electronic component is in operation, and substantially adheres on a boundary of an electronic component and a heat radiation component without a void.
