The purpose of the present invention is to provide a SiC semiconductor device having a property whereby the strength of the SiC semiconductor device can be increased as much as possible when the SiC semiconductor device (1) is cut from a SiC semiconductor wafer (11) by SnB technology. Correspondingly, a manufacturing method for manufacturing the SiC semiconductor device is provided. The SiC semiconductor device is obtained by forming a scribe line (L) on a SiC semiconductor wafer (11) by using a scribe tool and then applying an external force along the scribe line (L) to break the SiC semiconductor wafer (11). In a side wall surface of a SiC semiconductor device (1), a vertical pattern (TL) is formed which extends from a plastic deformation region of a Si surface and a predetermined depth other than a vertical crack region formed directly below the plastic deformation region to a C surface. The longitudinal lines (TL) satisfy either the following conditions: "straight line-shaped", and "when the lower surface is a C surface, the outer angle (theta) at the intersection between the longitudinal lines (TL) extending upward from the C surface and the bent lines (KL) formed by bending the longitudinal lines (TL) for the first time is within 10 degrees".
