Power semiconductor device

A power semiconductor device comprising:

• an insulating substrate;
• a semiconductor element having a lower surface bonded to said insulating substrate, and an upper surface having an electrode;
• a case forming a container body having a bottom surface defined by a surface of said insulating substrate, to which said semiconductor element is bonded;
• a plate-shape wiring member having a first portion integrated with said case, and a second portion positioned above said electrode of said semiconductor element in said container body, and extending sideward;
• and
• a sealing member filled in said container body to cover said wiring member in the container body, wherein
• said second portion of said wiring member is provided with a projection portion projecting toward said electrode of said semiconductor element and bonded to the electrode with a solder and a through hole passing through said second portion in a thickness direction through said projection portion.
