Abstract: A composite conducive to heat dissipation of an LED-mounted substrate includes a ceramic layer being of a thermal conductivity of 20˜24 W/mK; a metal layer being of a thermal conductivity of 100˜200 W/mK; and a graphite layer being of an in-plane thermal conductivity of 950 W/mK and a through-plane thermal conductivity of 3 W/mK, wherein the metal layer is disposed between the ceramic layer and the graphite layer. The composite has one side displaying satisfactory insulation characteristics and the other side displaying satisfactory heat transfer characteristics. The composite incurs low material costs and requires a simple manufacturing process.
