The present invention relates to a semiconductor device and a manufacturing method thereof. The semiconductor device has a plurality of power units placed in parallel in a predetermined direction, and integrally sealed with resin, wherein each of the power units includes a plurality of semiconductor elements placed on a metal plate having predetermined gaps with each other. Two of the power units placed adjacent to each other in the predetermined direction have a passage therebetween through which the resin flows injected during manufacturing. The semiconductor elements of each of the two power units include a near-sided semiconductor element that is closer to an inlet of the resin among the two semiconductor elements having the predetermined gap therebetween. A structure is positioned on a passage and downstream in a resin flow direction relative to a predetermined position that corresponds to end parts of the near-sided semiconductor elements such that the structure prevents the resin from flowing downstream in a resin flow direction, the end parts being on a side opposite to another side closer to the inlet.
