Abstract
A driving circuit for a switching element includes a main current wiring and a substrate. The main current wiring has a flat surface and carries a main current. The substrate has a flat surface mounted on the flat surface of the main current wiring and includes a coil disposed inside. The coil is disposed so as to interlink with a magnetic flux generated depending on the main current of the switching element and is electrically connected such that the coil receives the pulse signal of the signal source and transmits the pulse signal to a control terminal of the switching element.
