In a static induction transistor of tunnel injection type, a tunnel injection region is formed between its source region and channel region, and its gate region is formed of a semiconductor having a forbidden band larger than that of said channel region and contacting partially or wholly with the surface of said channel region. Such a transistor is also applied to an integrated circuit.
