Abstract: PROBLEM TO BE SOLVED: To provide a heterojunction field effect transistor of less source resistance and drain resistance, while excellent in high-output characteristics and noise characteristics. SOLUTION: There are provided, formed sequentially on a substrate 10, a channel layer 12 comprising InxGa1-xN (0<=x<=1), an electron supply layer 13 comprising AlyGa1-yN (0<y<=1), an intermediate layer 14, and an n-type cap layer 15 comprising GaN. A gate electrode 9 is so formed as to contact a gate insulating layer 13 while a source electrode 8S and drain electrode 8D are so formed as to contact the n-type cap layer 15. The intermediate layer 14 comprises at least one layer of n-type impurity layer.
