Claim 3:
4. The SiC substrate according to claim 1,
wherein, when resistivities at a plurality of third measurement points that are in the region inside the boundary located 5 mm inward from the outer circumferential end and that are separated by 10 mm from each of the plurality of the first measurement points in the [1-100] direction or the [−1100] direction, and at two fourth measurement points that are located 1 mm inward from the outer circumferential end and located in each of the [1-100] direction from the center and the [−1100] direction from the center are further measured, a difference between the maximum resistivity and the minimum resistivity among the resistivities of each of the plurality of first measurement points, the two second measurement points, the plurality of third measurement points, and the two fourth measurement points is 2 Ω·cm or less.
