Abstract
A SiC semiconductor device is provided that is capable of improving the detection accuracy of the current value of a principal current detected by a current sensing portion by restraining heat from escaping from the current sensing portion to a wiring member joined to a sensing-side surface electrode. The semiconductor deviceincludes a SiC semiconductor substrate, a source portionincluding a principal-current-side unit cell, a current sensing portionincluding a sensing-side unit cell, a source-side surface electrodedisposed above the source portion, and a sensing-side surface electrodethat is disposed above the current sensing portionand that has a sensing-side padto which a sensing-side wire is joined, and, in the semiconductor device, the sensing-side unit cellis disposed so as to avoid being positioned directly under the sensing-side pad
