Claim 12:
13. A method for manufacturing a circuit board including steps of:
arranging a plurality of conductive plates at a predetermined position of a metal mold, injecting resin into the metal mold to form a holding member having a number of recesses that corresponds to a position of a corresponding number of circuit components to be mounted, while forming the plurality of conductive plates and the holding member in one piece, wherein the circuit component includes a plurality of semiconductor switches, and a number of the recesses is at least the number of the semiconductor switches;
applying a conductive material in a region of the conductive plates on which a terminal of a circuit component is to be mounted;
aligning the terminal of the circuit component with the conductive material and mounting the terminal of the circuit component on the conductive plate,
introducing and heating, in a reflow furnace, the plurality of conductive plates and the holding member formed in one piece in a state where the circuit component is placed, melting the conductive material to solder the terminal of the circuit component to the conductive plate; and
attaching the heat dissipation plate on which a heat conductive member is applied on one side to a surface of the plurality of conductive plates and the holding member formed in one piece, on which the recess is formed.
