The thermally conductive resin sheet of the present invention has a heat conductivity of 7 W/m·K or more, a 30% compressive strength of 1500 kPa or less, and a rate of change of the 30% compressive strength of 30% or less after a heat resistance test in which the thermally conductive resin sheet is heated for 1000 hours at 150° C. According to the present invention, a thermally conductive resin sheet with good heat conductive property and flexibility and long-term stability of physical properties such as not becoming hardened over time can be provided.
