Abstract
A semiconductor device according to an embodiment includes first to third semiconductor regions, a structure body, a gate electrode, and a high resistance part. The structure body includes an insulating part and a conductive part. The insulating part is arranged with the third semiconductor region, the second semiconductor region, and a portion of the first semiconductor region. The conductive part is located in the insulating part. The conductive part includes a portion facing the first semiconductor region. The high resistance part is located in the first semiconductor region and has a higher electrical resistance than the first semiconductor region. A plurality of the structure bodies includes first to third structure bodies. The second and third structure bodies are next to the first structure body. The high resistance part overlaps a circle center of an imaginary circle passing through centers of the first to third structure bodies.
