Abstract
Gates of a plurality of semiconductor switching elements are electrically connected to a common gate control pattern by gate wires. Sources of the plurality of semiconductor switching elements are electrically connected to a common source control pattern by source wires. The gate control pattern is disposed to interpose the source control pattern between the gate control pattern and each of the plurality of semiconductor switching elements that are connected in parallel and that operate in parallel. Hence, each of the gate wires becomes longer than each of the source wires, and has an inductance larger than the source wire. Accordingly, gate oscillation is reduced or suppressed in the plurality of semiconductor switching elements that are connected in parallel and that operate in parallel.
