Abstract
A laminated wiring has a first conductor which connects first terminals of one or more capacitors and each positive terminal of a plurality of semiconductor modules, a second conductor which connects second terminals of the one or more capacitors and each negative terminal of the plurality of semiconductor modules, and an insulator. Slits are cut in at least one of the first conductor and the second conductor (in both of them in the example of FIG.). By doing so, among the plurality of semiconductor modules, a variation in the total of respective inductance values between respective first terminals and one positive terminal closest to the respective first terminals and respective inductance values between respective negative terminals to one second terminal closest to the respective negative terminals becomes smaller than or equal to 10 nH.
