Thermally conductive sheet, heat dissipation device, and method for producing thermally conductive sheet

A thermal conductive sheet, comprising:

• a thermal conductive layer comprising at least one graphite particle (A) selected from the group consisting of a scale-like particle, an ellipsoidal particle, and a rod-like particle, wherein, in a case of the scale-like particle, a plane direction of the scale-like particle is oriented in a thickness direction of the thermal conductive layer, in a case of the ellipsoidal particle, a longitudinal direction of the ellipsoidal particle is oriented in the thickness direction of the thermal conductive layer, and in a case of the rod-like particle, a longitudinal direction of the rod-like particle is oriented in the thickness direction of the thermal conductive layer;
• and
• an adhesion layer that comprises a resin component and a thermal conductive filler comprising a first thermal conductive filler having an average particle size of 500 nm or less, and that is located at least at one portion of a main surface of the thermal conductive layer.
