Press - contact type semiconductor device

A press-contact type semiconductor device comprising:

• a plurality of semiconductor elements each of which has a first main electrode and a control electrode on a front surface thereof and a second main electrode on a rear surface thereof;
• a second common main power source plate having said semiconductor elements positioned on a front surface thereof and electrically connected to said second main electrodes of said semiconductor elements;
• a first common main power source plate arranged on said front surfaces of said semiconductor elements and electrically connected to said first main electrodes of said semiconductor elements;
• a common control signal/main current plate arranged between semiconductor elements and comprising at least control signal wiring layers electrically connected to said control electrodes and main current wiring layers electrically connected to said first main electrodes;
• conductive connectors for electrically connecting at least said main current wiring layers and said first common main power source plate;
• and
• conductive elastic members configured to connect electrically said main current wiring layers or said first common main power source plate to said conductive connectors by elasticity.
