Patent ID: 7403397

Claim:
A switching power-supply module, comprising: 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; and conductor terminals interconnecting the conductor land patterns; wherein the circuit boards are stacked with spacing therebetween such that the conductor land patterns are aligned, and the aligned conductor land patterns are interconnected by the corresponding conductor terminals; and at least one of the conductor terminals includes an interboard-connection portion interconnecting the conductor land patterns of the circuit boards and a leg portion that extends from the interboard-connection portion in a stacking direction of the circuit boards and that defines an external-connection portion thereby defining an interboard-connection/external-connection terminal arranged to provide connection between the circuit boards and to provide external connection, and each conductor terminal other than the at least one conductor terminal defines an interboard-connection dedicated terminal arranged to provide connection between the circuit boards.
