To provide a thermally conductive sheet that has high thermal conductivity.A method for producing a thermally conductive sheet S includes a step of obtaining a thermally conductive composition by mixing a reactive liquid resin, which forms a rubbery or gelatinous matrix when crosslinked, a volatile liquid having a boiling point 10° C. or more higher than a curing temperature of the reactive liquid resin, and a thermally conductive filler; a step of forming a molded body by crosslinking and curing the reactive liquid resin at a temperature 10° C. or more lower than the boiling point of the volatile liquid; and a step of evaporating the volatile liquid by heating the molded body, in which these steps are performed sequentially. |
