A metal-ceramic composite substrate having excellent heat dissipation and a method of manufacturing such a metal-ceramic composite substrate at low cost are disclosed. A metal-ceramic composite substrate (10) comprises a metal substrate (11), a ceramic layer (12) formed on the metal substrate (11), an electrode layer (13) formed on the ceramic layer (12) and a solder layer (14) formed on the electrode layer (13) wherein the ceramic layer (12) is in the form of a thin film of a ceramic. Forming the ceramic layer (12) in the form of a thin film of aluminum nitride provides a metal-ceramic composite substrate (10) of excellent heat dissipating property for an electronic circuit.
