The present invention provides a thermally conductive sheet with high thermal conductivity. As a method for producing the thermally conductive sheet S, a reactive liquid resin that forms a rubber or gel-like matrix by crosslinking, a volatile liquid having a boiling point higher than the curing temperature of the reactive liquid resin by 10° C. or more, and a thermally conductive filler are sequentially mixed. The step of obtaining a thermally conductive composition, the step of crosslinking and curing the reactive liquid resin at a temperature 10° C. or more lower than the boiling point of the volatile liquid to form a molded body, and heating the molded body to make the volatile liquid The process of liquid volatilization. |
