Disclosed herein is a heat-radiating substrate. The heat-radiating substrate includes: a metal core layer; a first insulating layer that is formed on one side or both sides of the metal core layer, includes a bather layer contacting with the metal core layer, first and second pores having different diameters, and a porous layer connected with the bather layer; a first circuit layer that is embedded in the first insulating layer, filled in the second pores of the porous layer, and connected to the sides of the second pores; and a second insulating layer that is formed on the porous layer of the first insulating layer. Further, in the heat-radiating substrate of the present embodiment, the first circuit layer is partially filled in the second pores and the second insulating layer is filled in the second pores to make a plane the first insulating layer. In addition, disclosed is a method of manufacturing the heat-radiating substrate.
