Abstract
A semiconductor module forming a semiconductor device includes lead frames in which switching elements are mounted on the side of upper surfaces and heat radiation surfaces are formed on the side of lower surfaces, and bus bars disposed on the lead frames and connecting between plural switching elements. The heat radiation surfaces of the lead frames are arranged on one plane and upper surfaces of flat surface portions of the bus bars are arranged on one plane, therefore, a layout property on the heat radiation surfaces or the upper surfaces the flat surface portions is good, which facilitates creation of a heat radiation structure and so on.
