Provided is a thermally-conductive sheet having high thermal conductivity. This method for producing a thermally-conductive sheet S, comprises: a step for obtaining a thermally-conductive composition by mixing a reactive liquid resin which becomes a rubber or a gel matrix by being crosslinked, a volatile liquid having a boiling point which is at least 10°C higher than the curing temperature of the reactive liquid resin, and a thermally-conductive filler; a step for forming a molded article by crosslinking and curing the reactive liquid resin at a temperature which is at least 10°C lower than the boiling point of the volatile liquid; and a step for heating the molded article to volatilize the volatile liquid, wherein these steps are successively performed. |
