Abstract
The side surface has a first outer end surface. The bottom surface has a first bottom portion continuous to the first outer end surface, and a second bottom portion continuous to the first bottom portion and located on a side opposite to the inner end surface with respect to the first bottom portion. A silicon carbide substrate has a first region and a second region located between the at least one gate trench and a second main surface, and spaced from each other with a drift region being sandwiched therebetween. In a direction parallel to the first outer end surface, a spacing between the first region and the second region located between the first bottom portion and the second main surface is smaller than a spacing between the first region and the second region located between the second bottom portion and the second main surface.
