NOVELTY - The invention claims a heat-conducting insulating graphene, comprising a graphene block orderly stacked by multiple layers of graphene film, adjacent graphene films are connected by adhesive layer; the graphene block is penetrated and fixed with heat conducting fibre along the lamination direction; the opposite to the surface block is fixedly provided with an insulating layer, the thickness direction of the insulating layer is vertical to the lamination direction of the graphene film, the insulating layer contains anisotropic magnetic boron nitride. In the invention, after the graphene film is laminated, the heat-conducting fibre is penetrated and fixed along the lamination direction, so that the horizontal direction and the interlayer direction of the heat-conducting insulating graphene are provided with good heat-conducting performance and mechanical property; graphene boron nitride is covered surface a magnetic boron nitride, the magnetic boron nitride exhibits high thermal conductivity and excellent insulating performance after the orientation of the magnetic boron nitride; thus, the graphene
