Abstract
A CR snubber circuit capable of increasing a reduction effect of the effective inductance component and suppressing a ringing component generated at the time of switching the switching element is obtained. A first current path formed on one surface of the substrate and a second current path formed on the other surface, which is the opposite side of the one surface of the substrate, are opposed to each other with the substrate being sandwiched therebetween, and the capacitorand the resistorare arranged such that current flows in opposite directions in the first current path and the second current path, and a band elimination filter is formed by the capacitor, the resistor, and an effective inductance component obtained by coupling an inductance component included in the first current path and an inductance component included in the second current path.
