Semiconductor device

A semiconductor device comprising:

• an insulating substrate having a first metal layer and a second metal layer on a surface of the insulating substrate;
• a semiconductor chip including an upper electrode and a lower electrode, the upper electrode being electrically connected to the first metal layer, the lower electrode being electrically connectable to the second metal layer;
• a first main terminal including a first end and a second end, the first end being electrically connected to the first metal layer;
• a second main terminal including a third end and a fourth end, the third end being electrically connected to the second metal layer;
• a first detection terminal being electrically connected between the first end and the second end of the first main terminal;
• and
• a second detection terminal being electrically connected to the first metal layer, the second detection terminal being separated from the first detection terminal,
• wherein the second detection terminal is fixed to the first metal layer.
