NOVELTY - The device has a first semiconductor element which is provided between conductors. One end of first power terminal is connected to the second conductor, while extending other end of first power terminal as more outwardly from second conductor. A second power terminal is provided for connecting first conductor and fourth conductor and extending more away than first conductor and fourth conductor. One end of the third power terminal is connected to third conductor, while making other end of third power terminal extending more outwardly than third conductor.    USE - Semiconductor device used as semiconductor modules in power converter used in hybrid vehicle and electric vehicle.    ADVANTAGE - Since the conductors are connected to front and back surfaces of a semiconductor element, and the heats are radiated from the respective conductors to a cooler, the miniaturization and high reliability of the power converter is achieved by densely arranging the semiconductor modules with high cooling efficiency.    DETAILED DESCRIPTION - The semiconductor device has a first semiconductor element that is comprised with a first electrode connected with first conductor, a second electrode connected with second conductor and a control electrode connected with first signal terminal. A second semiconductor element is provided between the first conductor and second conductor, and comprised with a first electrode connected with first conductor, and a second electrode connected with the second conductor.
