(57) [Abstract] [Problem] Thermal conductivity of 2 W / mK or more, Asker C hardness of 60 To provide a heat-radiating spacer having high flexibility and high thermal conductivity. The heat radiation spacer is characterized in that a pine box-like boron nitride obtained by assembling flake-like primary particles of hexagonal boron nitride without being oriented is contained in an addition-reaction type liquid silicone solidified product. |
