    摘要: According to one embodiment, a nitride semiconductor includes a nitride member. The nitride member includes a first nitride region including Alx1Ga1-x1N, a second nitride region including Alx2Ga1-x2N, and a third nitride region including Alx3Ga1-x3N. The second nitride region is provided between the first and third nitride regions in a first direction from the first nitride region to the second nitride region. The second nitride region includes carbon and oxygen. The first nitride region does not include carbon, or a second carbon concentration in the second nitride region is higher than a first carbon concentration in the first nitride region. The second carbon concentration is higher than a third carbon concentration in the third nitride region. A ratio of a second oxygen concentration in the second nitride region to the second carbon concentration is not less than 1.0 × 10-4 and not more than 1.4 × 10-3.
