Abstract
A switching module includes a series-connected unit of a first flowing restriction element and a second flowing restriction element, the first flowing restriction element having an opening and closing function of opening and closing a flowing path of current, and the second flowing restriction element having at least one of a rectifying function of restricting the direction in which current flows and the opening and closing function, and a snubber circuit connected to the series-connected unit in parallel. A first wiring line connecting between the first flowing restriction element and the snubber circuit, a second wiring line connecting between the second flowing restriction element and the snubber circuit, a third wiring line connecting between the first flowing restriction element and the second flowing restriction element, the first flowing restriction element, the second flowing restriction element, and the snubber circuit are formed substantially integrally with each other by using an insulator.
