Power semiconductor device

A power semiconductor device, comprising:

• a substrate on which a semiconductor chip is disposed;
• an electrode which has one end fixed to the substrate and stands upright on the substrate;
• an insulating case which houses the electrode and has a part opposed to another end of the electrode;
• a conductive nut which is inserted into the case in the part of the case;
• and
• a conductive component which electrically connects the another end of the electrode and the nut, wherein
• one end of the conductive component is connected to the another end of the electrode, and
• another end of the conductive component is attached to the nut only partway.
