A switching power-supply module includes circuit boards, power conversion circuit sections provided on the respective circuit boards, conductor land patterns provided with spacing therebetween along edges of the circuit boards, conductor terminals for interconnecting the conductor land patterns. The circuit boards are stacked with spacing therebetween with the corresponding conductor land patterns being aligned, and the aligned conductor land patterns are interconnected by the corresponding conductor terminals. At least one of the conductor terminals includes an interboard-connection portion for interconnecting the conductor land patterns of the circuit boards and a leg portion that extends from the interboard-connection portion in the stacking direction of the circuit boards and that defines an external-connection portion, and the other conductor terminals each function as an interboard-connection dedicated terminal for providing connection between the circuit boards.
