Claim:
1. A semiconductor device comprising: an active region disposed on a semiconductor substrate; and an edge termination structure region disposed on the semiconductor substrate to surround the active region, wherein the active region includes the edge termination structure region includes the second second-conductivity-type semiconductor region is in contact with the first electrode, among the plurality of the third second-conductivity-type semiconductor regions, at least the third second-conductivity-type semiconductor region closest to the active region is electrically connected to the second second-conductivity-type semiconductor region under a gate runner disposed above the semiconductor substrate in the vicinity of the boundary between the active region and the edge termination structure region, and the second second-conductivity-type semiconductor region is formed directly on the first second-conductivity-type semiconductor region in a depth direction and on the side opposite to a side of the first-conductivity-type semiconductor layer.
