When a nut housing member is inserted from a first opening portion into a case (terminal housing area) in a semiconductor device, first and second protrusions of the nut housing member slide on and pass through the first and second opening portions. Ultimately, the nut housing member is housed in the case (terminal housing area), with the first protrusion being in contact with a lower end of the second opening portion and the second protrusion being in contact with a lower end of the first opening portion. Even if the nut housing member is not inserted in parallel with the terminal housing area, the forefront does not hit against a first beam. Therefore, the nut housing member is inserted stably and housed reliably in the terminal housing area of the case, and the assemblability of the nut housing member with respect to the case is improved. |

1. A semiconductor device, comprising:
a laminated substrate having an insulating board, and a circuit board disposed over a principal plane of the insulating board; a semiconductor chip disposed over the circuit board, and having a control electrode; a control terminal having a fixed portion with a first surface and a second surface opposite the first surface, the control terminal being disposed over the circuit board, and being electrically connected to the control electrode; a case disposed on a principal plane side of the insulating board, and covering the circuit board and the semiconductor chip, the case having
an upper surface,a side surface that connects with the upper surface,a first beam formed on the upper surface and being disposed inside of the case,a first opening portion formed in the side surface,a second opening portion formed in the first beam and opposite the first opening portion, anda terminal housing area between the first opening portion and the second opening portion for housing the control terminal, the first surface of the fixed portion being exposed from the terminal housing area on an upper surface side; and a nut housing member which has a third surface, a fourth surface opposite the third surface, a first protrusion disposed on a front side of the fourth surface, a second protrusion disposed on a back side of the fourth surface, and a concavity disposed between the first protrusion and the second protrusion, the nut housing member being adapted to house a nut, wherein the nut housing member is inserted from the first opening portion, through a second surface side of the fixed portion, and into the second opening portion, the first protrusion being brought into contact with a lower end of the second opening portion, and the second protrusion being brought into contact with a lower end of the first opening portion. |
