Original Abstract Submitted
The first area density is 0.03/cmor more, and a value obtained by dividing the second area density by a sum of the first area density and the second area density is 10% or less. As viewed in a direction perpendicular to the main surface, the first recess extends in a straight line along a direction inclined with respect to each of the first direction and a second direction perpendicular to the first direction, and a first-direction-side end portion of the first recess is contiguous to a 4H polytype region, and as viewed in the direction perpendicular to the main surface, the second recess extends in a straight line along a direction inclined with respect to each of the first direction and the second direction, and a first-direction-side end portion of the second recess is contiguous to a 3C polytype region.
