Zusammenfassung:	To reduce a loss due to a negative bias voltage in a driving circuit of a switching element.SOLUTION: A Vout terminal 123 of a drive circuit 12 is connected to a gate terminal of a switching element 1 via a capacitor 11 and a resistance 13 connected in parallel. A Vee terminal 124 of the drive circuit 12 is connected to a source terminal of the switching element 1 via a capacitor 14 and a resistance 14 connected in parallel.SELECTED DRAWING: Figure 1 【課題】スイッチング素子の駆動回路において、負バイアス電圧による損失を低減することを目的とする。【解決手段】スイッチング素子１のゲート端子には、並列に接続されたコンデンサ１１及び抵抗１３を介してドライブ回路１２のＶｏｕｔ端１２３が接続される。スイッチング素子１のソース端子には、並列に接続されたコンデンサ１４及び抵抗１４を介してドライブ回路１２のＶｅｅ端１２４が接続されている。【選択図】図１
