PROBLEM TO BE SOLVED: To provide a metal base circuit board which is surface-mounted on a wiring board while keeping an advantage that is excellent heat radiation performance.SOLUTION: A metal base circuit board 1 has a structure where a circuit layer 4 is laminated on a base metal 2 through an insulation layer 3. Both end parts 11, 12 are folded so that the base metal 2 is located at the inner side. In both end parts 11, 12, a pair of electrodes 6, 7 is exposed so that the circuit layer 4 is electrically connected with a wiring board 5 when the metal base circuit board 1 is mounted on the wiring board 5. The structure enables the electrodes 6, 7 to contact with circuit wiring 5a, 5b of the wiring board 5 and establish electrical continuity therebetween when the metal base circuit board 1 is mounted on the wiring board 5. |
