Over surfaces on the first surface side, the side surface side and an outer peripheral portion on the second surface side of the semiconductor region, the layer is formed. An electrode of the one conductivity type is located on the second surface adjacent to the layer. The semiconductor substrate includes a trench located between the outer periphery of the second surface and an end of the electrode with a spacing from the electrode and configured to isolate the layer along the outer periphery of the second surface. When viewed from the second surface side, a shortest distance between the end of the electrode and the trench is smaller than a shortest distance between a junction of the layer of the side surface side and the trench.
