Abstract
To provide a switching device driving unit that can shorten a connecting distance between a driver and a semiconductor switching element, while ensuring the insulation between a driver and a cooling device, even in a case of employing a semiconductor switching element which is composed of wide gap semiconductor. The switching device driving unit includes a circuit board, a semiconductor switching element composed of wide band gap semiconductor, a cooling device and a driver. The driver is surface mounted on a second face, which is an opposite side face of a first face which is a face of the circuit board on a side where the cooling device is disposed.
