Abstract
According to one embodiment, the fifth semiconductor region contacts the first semiconductor region. The metal region is provided on the fifth semiconductor region. The first insulating film extends in a thickness direction of the semiconductor layer. The first insulating film is adjacent to the fourth semiconductor region, the third semiconductor region, the second semiconductor region, and the first semiconductor region. The second insulating film extends in the thickness direction of the semiconductor layer. The second insulating film is provided between the fourth semiconductor region and the first conductive unit, between the third semiconductor region and the first conductive unit, and between the second semiconductor region and the first conductive unit.
