Abstract
A nitride semiconductor device includes; a semiconductor stack configured with a plurality of semiconductor layers made of nitride semiconductors provided on a base having a conductive portion; a first electrode provided on a portion of a semiconductor layer of the semiconductor layers configuring the semiconductor stack; a second electrode provided on a portion of a semiconductor layer of the semiconductor layers configuring the semiconductor stack separately from the first electrode; a first wiring provided at an upper layer of the first electrode; and a second wiring provided at an upper layer of the second electrode. A low permittivity area being a portion of which permittivity is lower than permittivities of the nitride semiconductors configuring the semiconductor stack at a lower layer of a portion of at least one of the first electrode and the second electrode other than a portion being junctioned with the semiconductor stack electrically.
