Abstract
A switching element includes a gate electrode and a source electrode disposed in each of trenches provided in a semiconductor substrate. A longitudinal direction of the trench is defined as a first direction, and the trenches are spaced from each other in a second direction intersecting the first direction. Each of the trenches extends in the first direction while being displaced in the second direction so as to satisfy that an inter-trench region between the adjacent trenches has narrow portions and wide portions alternately arranged in the first direction and alternately arranged in the second direction via the trenches. A source region is distributed across the narrow portion and the wide portion, and is in contact with the source electrode in the wide portion.
