Abstract: The present invention is a thermally conductive sheet comprising a plurality of unit layers, each comprising a silicone resin and a thermally conductive filler, the plurality of unit layers being laminated such that the plurality of unit layers are adhered to each other, wherein a volume content of the silicone resin is 32% by volume or less, and a compressive load at a sheet area of 25.4 mm×25.4 mm when the thermally conductive sheet is 30% compressed from a direction perpendicular to an adhesion plane on which the plurality of unit layers are adhered to each other is 7.0 kgf or less. According to the present invention, it is possible to improve the thermal conductivity and enhance the softness of a thermally conductive sheet using a silicone resin as a matrix component and composed of a large number of unit layers laminated as compared with the conventional one.

Abstract: Provided is a thermally conductive sheet having high thermal conductivity not only in a thickness direction of the sheet but also in one direction along a plane direction of the sheet. The thermally conductive sheet is a thermally conductive sheet containing a scaly filler 12 in a polymer matrix 11, wherein the scaly filler 12 is oriented such that a long axis direction of a scale surface is along one of a first direction that is a thickness direction of the thermally conductive sheet and a second direction that is perpendicular to the first direction, and a transverse axis direction that is perpendicular to the long axis direction in the scale surface is along the other of the first direction and the second direction.
