Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a metal base circuit board superior in thermal conductivity at low cost. SOLUTION: An insulating layer 102 is formed on a metal substrate 101 by using solvent-soluble liquid-crystal polyester. Further, a conductive foil 103 for forming a wiring pattern is formed on the insulating layer 102. A light emitting component such as a light emitting diode is mounted on the metal base circuit board. By using the liquid-crystal polyester, it is possible to achieve the insulating layer 102 having very high thermal conductivity. Consequently, it facilitates transfer of heat, generated in the light emitting component, to the metal substrate 101. Accordingly, it improves the heat-dissipation effect by the metal substrate 101.
