Abstract:
A silicon carbide epitaxial substrate includes a silicon carbide single crystal substrate and a silicon carbide layer. The silicon carbide single crystal substrate has a first main surface. The silicon carbide layer is on the first main surface. The silicon carbide layer includes a second main surface opposite to a surface thereof in contact with the silicon carbide single crystal substrate. The second main surface has a maximum diameter of more than or equal to 100 mm. The second main surface includes an outer peripheral region which is within 3 mm from an outer edge of the second main surface, and a central region surrounded by the outer peripheral region. The central region has a haze of less than or equal to 75 ppm.

Claim (Index 5):
The silicon carbide epitaxial substrate according to  claim 4 , wherein\n the groove portion includes a first groove portion, and a second groove portion connected to the first groove portion, the first groove portion is at one end portion of the groove portion in the one direction, and the second groove portion extends from the first groove portion along the one direction to reach the other end portion opposite to the one end portion, and has a depth from the second main surface which is smaller than a maximum depth of the first groove portion.
