NOVELTY - The utility model claims a multi-layer radiating type ceramic substrate, comprising a main body, a lower line layer, an upper line layer, a lower graphene radiating layer and an upper graphene radiating layer; The main body comprises a lower ceramic base layer, an upper ceramic base layer and a carbon fibre insulating interlayer; and the upper and lower surface of the main body is formed with a through hole and a radiating hole, the through hole is filled with metal to form a conductive column, the radiating hole is filled with graphene material to form a radiating column; the carbon fibre insulating interlayer is clamped between the upper ceramic base layer and the lower ceramic base layer is fixed, so that the whole structure strength of the product is effectively enhanced, avoiding easy breaking damage which is good for prolonging the service life, at the same time, by matching with the lower graphene radiating layer and the graphene radiating layer, and the radiating column is connected between the lower graphene radiating layer and the graphene radiating layer, the heat generated by the electronic device can be quickly derived, the radiating effect is better, the product can be normally used for a long time.
