Semiconductor device

A semiconductor device comprising:

• a resin housing;
• a substrate having a wiring;
• a plurality of semiconductor elements each having a first main electrode disposed on a first surface, a second main electrode disposed on a second surface opposite to the first surface, and a pad disposed on the second surface, the first main electrodes being commonly joined to the wiring;
• and
• a signal terminal inserted in the housing, and electrically connected to the pads, wherein
• the signal terminal includes a branch terminal, and
• the branch terminal has a single first connection portion that projects from the housing to be connected to an external device, a plurality of second connection portions that are exposed from the housing and individually connected to the pads of the plurality of semiconductor elements, the pads having a same function, and a coupling portion that is disposed within the housing and electrically connects the first connection portion and the plurality of second connection portions.
