Abstract

The present invention disperses heating caused by an energizing current in a semiconductor device comprising a plurality of semiconductor elements positioned side by side in a row. This semiconductor device (1) comprises: a plurality of semiconductor elements (11) positioned side by side in a row; a first terminal (21) and second terminals (22); a first conductor (31) electrically connected to the first terminal (21) and the plurality of semiconductor elements (11); and a second conductor (32) electrically connected to the plurality of semiconductor elements (11) and the second terminals (22). The first terminal (21) is positioned on one side in the alignment direction of the plurality of semiconductor elements (11) with respect to the plurality of semiconductor elements (11), the first conductor (31), and the second conductor (32), and the second terminals (22) are positioned on the other side. The second conductor (32) has two divided pieces (32a) in which both sides, in the width direction that crosses the alignment direction and the thickness direction of the second conductor (32), extend in the alignment direction with respect to the plurality of semiconductor elements (11), and are each electrically connected to the plurality of semiconductor elements (11).
