A method of manufacturing a thermally conductive sheet

Comprising a method for producing a thermally conductive sheet made of a plurality of films bonded, comprising: preparing at least a substrate and a film disposed on the thermally conductive particles and containing a thermosetting resin on the substrate, a first substrate having and a second thin film with a base, so that the first and second film with the base material with a base of each of the thin-film contact, disposed opposed from the first roller pair and the second roller between the rolls, so that the pairs of first and second rollers rotating to apply pressure in the thickness direction of the film, and the film with a first substrate and a second substrate having the film conveyed to overlap.
