PROBLEM TO BE SOLVED: To reduce an inductance of a printed wiring board while avoiding the problem of an electrolyte leakage possible in the use of an electrolytic capacitor.SOLUTION: A plurality of capacitors are disposed on a first layer of the printed wiring board. The first layer of the printed wiring board is provided with a first positive pattern connecting positive electrodes of a plurality of power conversion means. A second layer of the printed wiring board is provided with a first negative pattern connecting negative electrodes of the plurality of power conversion means, second positive patterns branching from the first positive pattern and connected to respective positive electrodes of the plurality of capacitors, and second negative patterns branching from the first negative pattern and connected to respective negative electrodes of the plurality of capacitors. The second positive patterns and the second negative patterns are arranged in parallel. |
