Abstract
Provided is an inverterconfigured such that an electric component portionis integrated with a cooling portion. A switching moduleincludes a heat sinkjoined to the lower surface of a substrate. The cooling portionincludes an electric conductive coolerforming a refrigerant flow path. The switching moduleis attached to the coolersuch that a heat radiation portionof the heat sinkis exposed to the inside of the cooler. A common mode current suppression structureincluding an insulating member is interposed between the heat sinkand the coolerto electrically insulate the heat sinkand the coolerfrom each other.
