A semiconductor device includes: a case having an opening; a semiconductor element contained in the case; a control substrate which is disposed above the semiconductor element in the case and on which a control circuit to control the semiconductor element is disposed; a lid to cover the opening of the case; and a control terminal having one end portion connected to the control circuit disposed on the control substrate and the other end portion protruding out of the case. The control terminal has a bend in the case, and a side portion of the case or the lid is provided with a support capable of supporting the bend.
