The present invention is a thermally conductive sheet containing matrix resin and thermally conductive particles, and contains 200 parts by volume or more of thermally conductive particles relative to 100 parts by volume of the matrix resin component. The matrix resin component is cross-linked without the thermally conductive particles. The viscosity of the polymer after the reaction is 500 Pa·s or less at 25°C, the thermal conductivity of the thermal conductive sheet is above 2.0 W/m·K, and the 50% compression load value of the thermal conductive sheet with an initial thickness of 1.5 mm is at a compression speed of 5.0 When compressing in mm/min, the maximum load value is 100 kPa or more, and the load value after 1 minute is greater than 0 kPa and less than 100 kPa. Thereby, a thermal conductive sheet with high thermal conductivity, low stable load value and softness is provided. |
