Patent ID: 8592689

Claim:
A voltage conversion module, comprising: multilayer wiring board which has a plurality of wiring patterns stacked in sequence separately from one another, insulating members each positioned between the plurality of wiring patterns, and interlayer connection bodies electrically connecting the plurality of wiring patterns; a voltage conversion IC to perform voltage conversion, the voltage conversion IC mounted to one of the wiring patterns positioned in an inner side among the plurality of wiring patterns; a first capacitor in an input side and a second capacitor in an output side, the first capacitor and the second capacitor being mounted on a main surface of the multilayer wiring board and having electrode portions on both ends electrically connected to the voltage conversion IC via the plurality of the wiring patterns and the interlayer connection bodies; and an output side inductor which has electrode portions on both ends electrically connected to the second capacitor in series on the main surface of the multilayer wiring board, wherein one of the electrode portions in the first capacitor constitutes an input section and one of the electrode portions of the inductor constitutes an output section; and wherein the other of the electrode portions in the first capacitor or one of the electrode portions in the second capacitor is positioned between the input section and the inductor, and the other of the electrode portions in the first capacitor or the one of the electrode portions in the second capacitor is electrically set to ground.
